I understand that to set it up, it is

y= ax+b / (x+3)(x-3).

I dont understand how to solve for a and b.

Put in the points. You have two points, and two unknowns.

(0,0)

0= 0+b / (0+3)(0-3).

Solving this easy: b is zero.

Now that you have b, next point

y= ax / (x+3)(x-3). ( 8/7, 8/7)

8/7= a 4

solve for a.

thank you so much for your help
