Question

Can someone help me through the steps for these two geometry questions?

1. Does the point (-2,3) lie on the circle?
(x+2)^2 + (y-3)^2 =2

2. Find the center and radius of the equation.
(x+1)^2 + (y-6)^2 =9

Answer 1

Also, I'm on a crappy mobile phone, so I apologize if my replies are slow or none at all.

Answer 2

for the first one, do you know the equation of a circle?
