What is the center of the circle represented by this equation?
x2 + (y + 9)2 = 25
(3,5)
BE
(0,25)
(9,25)
(0, -9)

Answer 1

(0, -9).

Explanation:

The general form of the equation of a circle is:

(x - a)^2 + (y - b)^2 = r^2

where the center = (a, b).

x2 + (y + 9)2 = 25

Comparing this to the general form we see that the center = (0, -9).
