Compare the given equation
with
} This is the general form of the equation of a circle with its center at (h,k) and a radius of r.
So you can easily identify the center and radius of the given equation as:
Center at (3, -2) and radius of 3.
To graph the equation, you must first solve the equation for y:
Subtract from both sides.
Take the square root of both sides.
Subtract 2 from both sides.
and Now graph these two equations.
