7. Enlargement

The question provides the coordinates of the image points P'(4,6) and Q'(7,3) after an enlargement. However, the coordinates of the original points P and Q are not given in the problem statement.

To calculate the scale factor and the coordinates of the center of enlargement, we need at least two pairs of corresponding points (original and image). Since P and Q are missing, the problem cannot be solved with the information provided.
