Please help, how do I solve this problem?

**Reiny**, Monday, January 21, 2013 at 10:37amSince (-2,0) must be on the circle , (it is tangent to that point)

y must be either 4 or -4

first case: y = 4

centre is (-2,4) radius is 4

equation: (x+2)^2 + (y-4)^2 = 16

you try the other circle with centre (-2,-4)
