Devan Mays · Answer 2

(-9, 6)

Step-by-step explanation:

It's all about pattern matching.

A circle centered at (h, k) with radius r has the equation ...

(x - h) ^2 + (y - k) ^2 = r^2

Comparing this pattern to the equation you have, you can see that ...

h = - 9 k = 6 r = 10

Then the center is (h, k) = (-9, 6).
