The example moves the point (2,5) to (2,5) + (3,6) = (5,11)
Scaling
The coordinates are multiplied by a factor. For a geometric
figure where the points are scaled, this will give a smaller or
bigger figure. If the X and Y coordinates are scaled different-
ly this will alter the shape of the geometric figure.
