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

hi Missy - do you know the general formula for a circle? Plug in center for h,k and r
tell me what you got

Answer 2

(x – h)2 + (y – k)2 = r2
I get (x – 2)2 + (y + 1)2 = 64

Answer 3

you are absolutely correct.

Answer 4
