**Steve**, Friday, December 16, 2011 at 2:06pmThis one is fairly easy. The x-coordinates do not change, since we are rotating around a horizontal axis.

For the y-coordinates, just figure the distance above or below y=3, and change them to the same distance below or above.

(1,4) is 1 unit above y=3. Make it one unit below: (1,2)

similarly,

(3,6) -> (3,3-(6-3)) = (3,0)

(7,4) -> (7,3-(4-3)) = (7,2)
