r = 2 ; (h, k) = (4, -4)


Substitute 4 for h, -4 for k, and 2 for r



Simplify,multiply everything out, collect terms, and get
0 on the right:











Get 0 on the right by subtracting 4 from both sides:



The general form has the squared terms first, then the
x and y terms then the constant (number), then = 0
