I think (3,-6), but not real sure.

**Steve**, Monday, March 5, 2012 at 2:36pmthink of folding the diagram on the line y=3. x-values don't change, and y-values are moved the same distance from the line y=3.

The distance of (x,y) from (x,3) is y-3.

so, (x,y) --> (x,3-(y-3)) = (x,6-y)

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

D is 3 units above the line y=3, so it moves to 3 units below the line, or y=0.
