You can put this solution on YOUR website!
first you need to find the slope with the slope formula
m=%28y-y%29%2F%28x-x%29
m=%28%28-4%29-%28-2%29%29%2F%28%283%29-%286%29%29
m=%28-2%29%2F%28-3%29
m=2%2F3
then find the y-intercept with the slope/intercept formula
y=mx%2Bb Find B and then re-write with just slope and intercept.
y=%282%2F3%29x%2Bb imput a point
-4=%282%2F3%293%2Bb multiply
-4=2%2Bbsubtract
-6=b
rewrite
highlight%28y=%282%2F3%29x-6%29
