a circle has the equation
find the center and the radius of the euation. If there are any intercepts list them.
(x+3)^2 + (y-3)^2 = 64 = R^2
The origin is at x=-3 and y=3, and the radius is R=8
For the y intercept, set x=0 in the original equation and solve for y. For the x intercept, set y = 0 and solve for x.
