You can
put this solution on YOUR website!first get in the form y = mx + b where m is the slope
(1)

m = -2
the slope intercept form is:

pick any value for x. I'll pick -3
plug this into (1)

solve for y

so use the point (-3, 0) in the slope intercept form

this is the answer
check
multiply both sides by (x + 3)

that's what we started out with OK
