That circle description puts center 5 units away from the y-axis tangent point, so radius is 5.
%28x%2B5%29%5E2%2B%28y%2B2%29%5E2=25.

Substitute the coordinates for each point and check if the equation is true.
%28-2%2B5%29%5E2%2B%282%2B2%29%5E2=25
9%2B16=25
25=25
TRUE for the point (-2,2).

You can check the other point.
