Question

the diagram shows a dilation of line ab about the origin o. determine the scale factor of the dilation by following these steps. 1. measure these lengths: oa = 2.0 units, oa = 3.0 units. 2. measure these lengths: ob = units, ob = units. incorrect. the correct answer is shown. check

Explanation:

Step1: Identify points on graph

From graph, count grid - squares.

Step2: Measure lengths

OB = 4 units, OB' = 6 units.

Answer:

OB = 4, OB' = 6
