A circle with the equation (x+3)squared plus (y-2)squared = 25 is reflected over the line x=2. What is the equation of the image?

(x-3)^2 + (y+2)^2=25

(x-7)^2 + (y+2)^2=25

(x-7)^2 + (y-7)^2=25

(x-3)^2 + (y-2)^2=25

since the axis of reflection is vertical, the y-coordinates do not change.

(x,y) --> (2-(x-2),y) = (4-x,y)

The old center was (-3,2) so the new center is (7,2)

I don't see that as a choice. Typo in problem?
