, where is the gradient and the coordinates of the y-intercept.
What is the first step in writing an equation to solve the problem?
The following steps provide a good method to use when solving linear equations.
Simplify each side of the equation
by removing parentheses and combining like terms. Use addition or subtraction to isolate the variable term on one side of the equation. Use multiplication or division to solve for the variable.
How do I find the slope intercept form?
The equation of the line is written in the slope-intercept form, which is:
y = mx + b
, where m represents the slope and b represents the y-intercept. In our equation, y = 6x + 2, we see that the slope of the line is 6.
How do you find the slope of a linear function?
The slope of a linear function can be
calculated by dividing the difference between y-values by the difference in corresponding x-values of any two points on the line
. The slope and initial value can be determined given a graph or any two points on the line.

Answer:
y = 5x – 11
is the equation of the required line.
What is the equation of the line that passes through the point (- 2 1 and has a slope of 1?
Equation of the line passing through the point (2, 1) and having slope (-1) is given by;
y -1 = -1(x – 2)
.
What is the equation of the line which passes through 4?
4x+3y−1=0
.
How do you find the equation of a line from a graph?
To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept
(y=mx+b) form
. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points.
Which equation passes through origin?

What are the 3 types of equations?
The three main forms of an equation are
slope-intercept form, point-slope form, and standard form
. These equations give enough information about the line so that we can easily graph them.
What is the equation of a line passing through two points?
Since we know two points on the line, we use the two-point form to find its equation. The final equation is in the slope-intercept form,
y = mx + b
.
What comes first in solving equations?
In mathematics, the order of operations define the priority in which complex equations are solved. The top priority is
your parenthesis, then exponents, followed by multiplication and division, and finally addition and subtraction
(PEMDAS).
Where do you write equations?
- Choose Insert > Equation and choose the equation you want from the gallery.
- After you insert the equation the Equation Tools Design tab opens with symbols and structures that can be added to your equation.
What is an example of an equation in math?
An equation is a mathematical sentence that has two equal sides separated by an equal sign.
4 + 6 = 10
is an example of an equation. We can see on the left side of the equal sign, 4 + 6, and on the right hand side of the equal sign, 10.
How do I find the slope in a graph?
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-
coordinates (rise/run or slope).
