#(10,-7)#, #(-14,-7)#, #(-2,5)# or #(-2,19)#

Explanation:

Although any point on the circle, whose center is #(-2,-7)# and radius #12# could be the other point,

however, easiest way to get such points is

adding or subtracting #12# from ordinate or abscissa of the point #(-2,-7)#

and hence some such points are

#(10,-7)#, #(-14,-7)#, #(-2,5)# or #(-2,19)#
