Question

Circle P has a radius of 8 units with center P at (2, -1). Which equation defines circle P?

(x + 2)2 + (y – 1)2 = 64

(x – 2)2 + (y + 1)2 = 64

(x – 2)2 + (y + 1)2 = 8

(x + 2)2 + (y – 1)2 = 8

Answer 1

the general form of the circle is
\[(x -h)^2 + (y - k)^2 = r^2\]

(h, k) is the centre and r is the radius... your question has centre (2, -1) and r = 8

substitute to get your answer
