Answer: The scale factor of this dilation is 4/6, or 2/3.

Explanation:

The scale factor of a dilation is the ratio of the distances of the corresponding points after the dilation to the distances of the corresponding points before the dilation.

In this case, the distance between A and A' is 4 units (6-2=4). The distance between A and the origin (0,0) is 6 units.

Therefore, the scale factor of this dilation is 4/6, or 2/3.
