the equation of the circle:

%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2
if center at (3, -2) ==> h=3 and k=-2
%28x-3%29%5E2%2B%28y-%28-2%29%29%5E2=r%5E2
%28x-3%29%5E2%2B%28y%2B2%29%5E2=r%5E2
if solution point: (-1, 1)
%28-1-3%29%5E2%2B%281%2B2%29%5E2=r%5E2
16%2B9=r%5E2
r%5E2=25
your equation is %28x-3%29%5E2%2B%28y%2B2%29%5E2=25
