Question

The center of a circle represent by the equation (x+9)^2+(y-6)^2=10^2 is___. options.... (-9,6), (-6,9), (6,-9) ,(9,-6)

​

Answer 1

(-9, 6)

Explanation:

i took the test

Answer 2

(-9, 6)

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).
