Question

What is the equation of the circle with center (2, –5) that passes through the point (–2, 10)?

Answer 1

The choices are :
(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

Answer 2

Distance between center and point on circle = radius. Find that first.

Then, equation is:
(x - x1)^2 + (y - y1)^2 = r^2

Answer 3

Where x1, y1 is the center of circle.

Answer 4

(x – 2)2 + (y – (–5))2 = 241
