Lemme tell u a short cut :



whenever u see same  or same  in a  of points, you can be sure that it a triangle formed by the points.

And the  of  of the hypotenuse of triangle



In this case see   (-14,-1) and (-2,-1)  



              

Mid point = (10+(-4))/2 , (3+3)/2)

= (3,3)



Mid point = (-14+(-2))/2 , (-1+(-1))/2=-16/2,-2/2 =-8 , -1



Hence (-8 , -1) is the center of the circle
