Question

Find the scale factor for the dilation shown.The scale factor is16-12-8-GG04FE8FE1216

Answer 1

To find the scale factor we can use a ratio between the length of two segments, for exemple, the scale factor "k" will be

$k=\frac{D^{\prime}E^{\prime}}{DE}$

We can see in the graph that D'E' is 10, and DE is 5, therefore

$\begin{gathered} k=\frac{10}{5} \\ \\ k=2 \end{gathered}$

The scale factor is 2
