Question

The circle below is centered at the point (-1, 2) and has a radius of length 3.

What is its equation?
A. (x + 2)2 + (y - 1)2 =
O B. (x-1)2 + (y + 2)2 = 9
O C. (x+ 1)2 + (y-2)2 = 9
O D. (x- 2)2 + (y + 1)2 =

Answer 1

The answer is letter C. (x+1)² + (y-2)² = 9

Explanation:

(x-h)² + (y-k)² = r²

= (x-(-1))² + (y-2)² = 3²

= (x+1)² + (y-2)² = 9
