Given the point and it''s image, determine the scale factor.

A (3, 6) A'' (4.5, 9) G'' (3, 6) G (1.5, 3) B (2, 5) B'' (1, 2.5).

If the scale factor is more than 1, it is an enlargement, if it is less than 1, it is a reduction.

3.5 = enlargement
2/5 = reduction
0.6 = reduction
14.1 = enlargement
4/3 = enlargement
5/8 = reduction

For the next question,

Just divide the x-values(or y-values) of any points of the original to the new one.

4.5 / 3 = 1.5

So the scale factor is 1.5.
