Number one answers are a and c not a and d
1. The dilation is an enlargement, the dilation has a scale factor of 3
2. (3/4,-9/4)
3. x=-10 and y=2.5
4. 1.2 cm
5. -1/8
6. 30 units
7. 12 cm
8. X'(-7.5,3.5) and Y'(-2.5,-5.5)
9. For a dilation, corresponding angles of the image and preimage are congruent. A dilation with a scale factor is an enlargement.
