A circle with the equation (x+3)squared plus (y2)squared = 25 is reflected over the line x=2. What is the equation of the image?
(x3)^2 + (y+2)^2=25
(x7)^2 + (y+2)^2=25
(x7)^2 + (y7)^2=25
(x3)^2 + (y2)^2=25

since the axis of reflection is vertical, the ycoordinates do not change.
(x,y) > (2(x2),y) = (4x,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?
