After a dilation centered at the origin, the image of AB is

A’B’. If the coordinates of the endpoints of these segments are
A (6,-4),
B (2,-8)
A’ (9,-6), and
B’ (3,-12), what is the scale factor of the dilation?
1. 3/2
2. 1/2
3. 2/3
4. 3

9/6 = 3/2
check the other number pairs to be sure they all agree
