Question

What is the center of (x + 2)2 + y2 = 36?

Question 5 options:

(0, 2)


(2, 0)


(-2, 0)


(0, -2)

Answer 1

The equation for a circle is (x - h)^2 + (y - k)^2 = r^2
where (h,k) is the center and r is the radius
(x + 2)^2 + y^2 = 36
Is the same as
(x - -2)^2 +(y - 0)^2 = 6^2
the center is (-2,0)
