Question

The circle below is centered at the point (-2, 1) and has a radius of length 3. What is its equation? (Image) A. (x - 2)2 + (y + 1)2 = 3 B. (x + 1)2 + (y - 2)2 = 9 C. (x - 1)2 + (y + 2)2 = 3 D. (x + 2)2 + (y - 1)2 = 9

Answer 1

(x + 2)² + (y - 1)² = 9

Explanation:

(x - h)² + (y - k)² = r²

(x - (-2))² + (y - 1)² = 9

(x + 2)² + (y - 1)² = 9
