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

So:
%28x-1%29%5E2%2B%28y-%28-5%29%29%5E2=2.5%5E2

%28x-1%29%5E2%2B%28y%2B5%29%5E2=6.25

Or if you feel like expanding it:

x%5E2-2x%2B1%2By%5E2%2B10y%2B25-6.25=0

x%5E2%2By%5E2-2x%2B10y%2B19.75=0 putting it in Ax%5E2%2BBy%5E2%2BCx%2BDy%2BE=0 form
