the general equation is: ${\left( {x - a} \right)^2} + {\left( {y - b} \right)^2} = {r^2}$ where: a, and b are the x-coordinate and y-coordinate of the center, whereas r is the radius.

it is false briana...cuz the circle has not touche the point(-3,0)

in our case we have: $a = - 3,\quad b = 3,\quad r = 3$
