More than one way to do this. Look for the midpoint of any pair of opposite corners. Use distance formula to find half the length of a diagonal.
A pair of opposite corners is (-1,-3) and (-9,5).
Center point should be at and
Diagonal length,
HALF of that is . This is also the size of the radius of the circle.
Equation for the circle is .
