"find the center and radius for the circle. this is given (x-3)to the second power + (y+1)to the second power = 9.
--------------
Center is at (3,-1)
Radius is sqrt9 = 3

%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2 is a circle with center at (h,k) and radius r.

%28x-3%29%5E2%2B%28y%2B1%29%5E2=9

Let's change things a little:
%28x-3%29%5E2%2B%28y-%28-1%29%29%5E2=3%5E2

You should be able to take it from here. Write back if you are still having a problem.
