Question

Which equation is correct given the circle below?

Answer 1

i think the answer is A :)

Answer 2

(x - 2)² + (y + 1)² = 4

Explanation:

Since the coordinates are (2, -1), then the values would take the opposite sign of their sign. So positive becomes negative and negative becomes positive. The radius of the circle is 2. So, you'll have to square that number. 2² = 4.
