You can put this solution on YOUR website!
First you need to find the slope so use m=%28y2-y1%29%2F%28x2-x1%29
Point 1 (3,-5) is x1 and y1
Point 2 (o,-9) is x2 and y2
solve
m=%28y2-y1%29%2F%28x2-x1%29
m=%28%28-9%29-%28-5%29%29%2F%280-3%29
m=%28-4%29%2F-3 or 4%2F3 is your slope.
Next use point slope formula y-y1=m%28x-x1%29 to find the equation.
y-%28-5%29=%284%2F3%29%28x-3%29<---- multiply using distributive property
y%2B5=%28%284%2F3%29%28x%29%29%28%284%2F3%29%28-3%29%29
y%2B5=%284%2F3%29x-4
y=%284%2F3%29x-9 <----- your equation :)
