Use image to answer the question a 9, 9 b6, 6 a - 3, 3 d - 2, 2 determine the scale factor used in the dilation of line segment ad with a center point of dilation at origin 3 minus 1/3 1/3 - 3

The scale factor used in the dilation of line segment AD with a center point of dilation at the origin is 3.

This can be determined by comparing the lengths of the original line segment AD and the dilated line segment AD'. The image shows that the length of line segment AD' is 3 times longer than the original line segment AD, indicating a scale factor of 3.
