Use the rise over run formula to find the slope of the line.
Rise over run uses the following formula:
![\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%20)
Plug your points' x and y values into this formula:
(2,-4) and (4,4)
![\frac{4 -(-4)}{4-2} = \frac{8}{2} = 4](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%20-%28-4%29%7D%7B4-2%7D%20%3D%20%20%5Cfrac%7B8%7D%7B2%7D%20%3D%204)
The slope of the line is
4.To find the y-intercept of the line, we must take an x-value of a point, multiply it by our slope, and subtract that from the y-value:
(2,-4)
![2 \times 4 = 8](https://tex.z-dn.net/?f=2%20%5Ctimes%204%20%3D%208)
![-4 - 8 = -12](https://tex.z-dn.net/?f=-4%20-%208%20%3D%20-12)
The y-intercept is defined at
-12, at (0,-12).
Slope-intercept form uses the following formula:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
m is the slope of the line, and b is the y-intercept.
We have the values for the slope and y-intercept. Plug these values into the formula. The following equation is your answer:
