Center is on line x-2y%2B2=0
-2y=-x-2
y=x%2F2%2B1
and the center is some variable point ( x, x/2+1 ).

The two points ON the circle, (-1,-3) and (-5,3) are equally distant from center point ( x, x/2+1 ). Can you decide how to use the DISTANCE FORMULA to find x, and then the corresponding y, for the coordinates of the center?
