Answer 1

do you know general form of a circle?

Answer 2

x^2 + y^2 + Ax + By + C = 0

Answer 3

Yes

Answer 4

the center is ab.

Answer 5

so the center is A=-5 and B=0 right?

Answer 6

Yes

Answer 7

so lets put it in standard form first. (x-a)^2 + (y-b)^2 = r^2

Answer 8

(x+5)^2 + (y-0)^2= 4^2

Answer 9

now expand.
