In the standard form of a circle equation, (h,k) are the coordinates of the center and r is the radius.

Answer 2

(x-h)^2+(y-k)^2=9?

Answer 3

Not quite.

Answer 4

@dancingolivia

>>(x-h)^2+(y-k)^2=9? ---> You have to fill in for the center.

(x - (-4))^2 + (y - 2)^2 = 3^2

(x + 4)^2 + (y-2)^2 = 3^2
