You can put this solution on YOUR website!
find slope then slope intercept
know your equations m=%28y-y%29%2F%28x-x%29 y=mx%2Bb
m=%28y-y%29%2F%28x-x%29
m=%28-1-5%29%2F%283-%28-1%29%29
m=%28-6%29%2F%284%29
m=-3%2F2
use the slope to find the intercept
y=mx%2Bb insert knowns for m, x, y
-1=%28-3%2F2%293%2Bb%7D%7Dmultiply%0D%0A%7B%7B%7B-1=%28-9%2F2%29%2Bb add -9/2
%28-9%2F2%29%2B%28-2%2F2%29=b
%28-11%2F2%29=b
rewrite formula
y=mx%2Bb
y=%28-9%2F2%29x%2B%28-11%2F2%29
highlight%28y=%28-9%2F2%29x-11%2F2%29
