If PPP lies on a circle with centre CCC and radius rrr, what relationship holds?
A
CP=rCP=rCP=r.
B
There are no real points satisfying the equation.
C
(x+52)2+(y−1)2=334\left(x+\frac{5}{2}\right)^2+(y-1)^2=\frac{33}{4}(x+25)2+(y−1)2=433.
D
The circle (x+4)2+(y−7)2=36(x+4)^2+(y-7)^2=36(x+4)2+(y−7)2=36 has centre (−4,7)\boxed{(-4,7)}(−4,7).
