Question

Write the slope-intercept equation for the line that passes through (-4, 6) and (2, -6). Please show all of your work.

Answer 1

\[m=\frac{y_2-y_1}{x_2-x_1}\]

use one of the points \[(x_1,y_1)\]

and plug into
y=mx+b
\[y_1=mx_1+b\]
solve for b to find y-intercept

Answer 2

6+6/-4-2=12/-6=-2 so m=-2
6=-2(-4)+b
6=8+b
b=-2
so y=-2x-2

Answer 3

Thanks a lot, for explaining.
