You know that the choice must be either #1 or #3, since they have the proper center.
(-2,10) fits only choice #3.
What is the equation of the circle with center (2, –5) that passes through the point (–2, 10)?
(x – 2)2 + (y – (–5))2 = 25
(x – (–2))2 + (y – 10)2 = 241
(x – 2)2 + (y – (–5))2 = 241
(x – (–2))2 + (y – 10)2 = 25
