Question

what is the standered form of the equation of a circle with its center at (2, -3) and passing through the point (-2, 0) ?

Answer 1

(x-2)^2 + (y+3)^2 = r^2
plug in x = 2 and y = 0 in the equation above find r
and finally replace the value of r in above equation with r

Answer 2

I guess you can solve it now. Else, ask again.

Answer 3

r = 25
(x-2)^2 + (y+3)^2 = 25 answer
