You can put this solution on YOUR website!

the point-slope formula: y-y%5B1%5D=m%28x-x%5B1%5D%29
if (x%5B1%5D, y%5B1%5D) = (-2, 10) and (x%5B2%5D, y%5B2%5D) = (3, -5) are points on the line, slope is
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m=%28-5-10%29%2F%283-%28-2%29%29
m=%28-15%29%2F%283%2B2%29
m=%28-15%29%2F5
m=-3

=> y-y%5B1%5D=-3%28x-x%5B1%5D%29....plug in coordinates of one point

y-10=-3%28x-%28-2%29%29
y-10=-3%28x%2B2%29
y-10=-3x-6
y=-3x-6%2B10
y=-3x%2B4=> your line

This is basic.
Know how to do these.
Having someone do them for you won't help.
