yThe diagram shows a dilation of line ABabout the origin O. Determine the scalefactor of the dilation by following thesesteps.1. Measure these lengths:OA =unitsOA' =units2B0B4681012Α Α'-2.-4Check3456

Step 1: Concept
Dilation can be shrinks or stretches.
Step 2:
The pre-image AB was stretch to Image A'B'.
Step 3:
The length of OA may be 3 units, you can verify with your ruler
The length of OA' may also be 4 units, kindly confirm both lengths with your ruler.
