1.5
Step-by-step explanation:
You can see that the dilated figure (the figure in blue with the ‘) is larger than the original figure, so the scale factor or the dilation has to be a number that is 1 or higher.
Look at point Q. It is described as (1, 3) on the graph. Point Q’ is (1.5, 4.5). To know the dial ration, divide 1.5 by 1. You get 1.5 Divide 4.5 by 3 and you get 1.5.
The original figure is 1.5 times smaller than the dilated figure.
