Write the standard from of the equation and the general form of the equation of each circle of radius r and center (h,k);graph each circle.
(x-h)^2 + (y-k)^2 = r^2
-------------
The problem says: r=4; (h,k)=(2,-3)
(x-2)^2 + (y+3)^2 = 16

Standard Form of the Equation of a Circle:
Where (h,k) are the center of the cicle and r is the radius.
Your center is (2,-3) and r=4
General Form of the equation of the circle:
Expand the standard form and put it in order:
Happy Calculating!!!
