A coordinate is one of a set of numbers used to identify the location of a point on a graph. Each point is identified by both an x and a y coordinate.
What are the individual points called on a graph?
A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called links or lines). A distinction is made between undirected graphs, where edges link two vertices symmetrically, and directed graphs, where edges link two vertices asymmetrically.
What is each section of a graph called?
If you take a step back and look at this graph, you’ll see that the x and y-axes divide it into four parts. Each of these parts is called a quadrant . To make it easy to talk about quadrants, each one gets a number, starting from the first quadrant at the top right. In the first quadrant, both x and y are positive.
What is each line on a graph called?
The line graph comprises of two axes known as ‘x’ axis and ‘y’ axis . The horizontal axis is known as the x-axis. The vertical axis is known as the y-axis.
What is quadrant in graphing?
A quadrant is the area contained by the x and y axes ; thus, there are four quadrants in a graph. To explain, the two dimensional Cartesian plane is divided by the x and y axes into four quadrants. Starting in the top right corner is Quadrant I and in a counterclockwise direction you will see Quadrants II through IV.

What is graph terminology?
A graph is a collection of nodes also called vertices which are connected between one another. Each connection between two vertices is called an edge (sometimes called a branch).
What is the scale on a graph?
In simple words, a scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data . ... On the y-axis, the numbers are marked at intervals of 5. This indicates that the scale used for the graph is 1 unit is 5 children.
What is the top axis called?
A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis . The point where the x- and y-axis intersect is called the origin.
What is a vertical line called on a graph?
In a coordinate plane, a line parallel to the Y-axis is called Vertical Line. It is a straight line which goes from top to bottom and bottom to top. Any point in this line will have the same value for the x-coordinate.
How do you describe a line graph?
A line graph is a graphical display of information that changes continuously over time . Within a line graph, there are various data points connected together by a straight line that reveals a continuous change in the values represented by the data points.
What is quadrant or axis?
Quadrant is the region enclosed by the intersection of the X-axis and the Y-axis . On the cartesian plane when the two axes, X-axis and Y-axis, intersect with each other at 90 o there are four regions formed around it, and those regions are called quadrants.
What is a horizontal line called on a graph?
Thus the horizontal lines in the graph are called the x –axis .
What is second quadrant?
Quadrant II: The second quadrant happens to be in the upper left-hand corner of the plane . Moreover, X has negative values in this quadrant and y has positive values. ... Furthermore, both x and y have negative values in this quadrant. Quadrant IV: The fourth quadrant is in the bottom right corner of the plane.
Which is the 4th quadrant of a graph?
Quadrant IV: The fourth quadrant is in the bottom right corner . X has positive values in this quadrant and y has negative values.

What are different ways of representing graphs?
A graph can be represented using 3 data structures- adjacency matrix, adjacency list and adjacency set . An adjacency matrix can be thought of as a table with rows and columns.
What are the 3 parts of bar graph?
- Title: The title is explains what the graph is about.
- Scale: The scale is the numbers that show the units used on the bar graph.
- Labels: Both the side and the bottom of the bar graph have a label that tells what kind of data is shown. ...
- Bars: The bar is measures the data number.
What is matrix representation of graph?
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph . The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. ... If the graph is undirected (i.e. all of its edges are bidirectional), the adjacency matrix is symmetric.
What is graph terminology in graph theory?
Definition: Graph is a mathematical representation of a network and it describes the relationship between lines and points . A graph consists of some points and lines between them. ... Description: A graph ‘G’ is a set of vertex, called nodes ‘v’ which are connected by edges, called links ‘e’. Thus G= (v , e).
What is a label on a graph?
In the mathematical discipline of graph theory, a graph labelling is the assignment of labels, traditionally represented by integers, to edges and/or vertices of a graph. ... For many applications, the edges or vertices are given labels that are meaningful in the associated domain.
Where is the scales on a graph?
In general, the scale of the graph can differ between axes, but within an axis, such as on the x-axis of the coordinate plane, each interval represents the same value. Most typically, each mark on the x- and y-axes of the coordinate plane represents 1 unit, as shown in the figure below.
What is the scale of an axis on a graph?
The scale of an axis is the units into which the axis is divided . The units are marked by ticks, labels, and grid lines. When you change an axis’ scale, you change how the ticks, labels, and grid lines will display.
How do you read points on a graph?
Points are identified by stating their coordinates in the form of (x, y) . Note that the x-coordinate always comes first. For example, in the figure we’ve been using, we have identified both the x and y coordinate for each of the points B and D. The x-coordinate of point B is 100.
What is vertical point?
In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point . Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction.
What is it called when a graph goes up?
So far, all of the graphs discussed have had a line that either always goes up or always goes down (the technical term for this is monotonic ). Other relationships are more complex, with lines than can go up and down (called non-monotonic).
How do you describe a curve on a graph?
A curve is common in rates of reaction graphs . A straight line would indicate a constant rate of reaction, while a curve indicates a change in the rate (or speed) of a reaction over time. ... Lines of best fit are also useful in identifying anomalous results and outliers which will not lie on the line of best fit.
What are the coordinates of a point?
The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane . Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located.
What the line XOX is called?
The horizontal line XOX′ is called x-axis . ▪ The vertical line YOY′ is called y-axis.
What are relationships in graphs?
A direct relationship is when one variable increases , so does the other. An indirect relationship is when one variable increases, the other decreases. A cyclic relationship repeats itself over time. When the line on the graph always eventually comes back to the same place.
What is the 3rd quadrant in graphing?
The third quadrant, the lower left-hand corner, includes negative values of both x and y . Finally, the fourth quadrant, the lower right-hand corner, includes positive values of x and negative values of y.
What are the quadrant numbers on a graph?
The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the (x; y) coordinates are I (+; +), II (−; +), III (−; −), and IV (+; −).
What are the 4 quadrants on a coordinate plane?
Quadrant one (QI) is the top right fourth of the coordinate plane, where there are only positive coordinates. Quadrant two (QII) is the top left fourth of the coordinate plane. Quadrant three (QIII) is the bottom left fourth. Quadrant four (QIV) is the bottom right fourth .
