Use the graph to answer the question.

Graph of a polygon ABCD with vertices at 6 comma 3, 15 comma 3, 15 comma 9, 6 comma 9 and a second polygon A prime B prime C prime D prime with vertices at 2 comma 1, 5 comma 1, 5 comma 3, 2 comma 3.

Determine the scale factor used to create the image.

3
one third
one half
2

The scale factor used to create the image is 2. This can be determined by comparing the distance between corresponding vertices of the two polygons. For example, the distance between A and B in the original polygon is 9 units, while the distance between A' and B' in the second polygon is 3 units. This means that each unit in the original polygon is equivalent to 2 units in the image, resulting in a scale factor of 2.
