Question

Point A is a vertex of a polygon. Point R is the image of A after the dilation. Find the scale factor ofthe dilation.A(-2,-3) and R (-10,-15)

Answer 1

To find the dilatation factor we can divide the componets so:

$\begin{gathered} \frac{-2}{-10}=0.2 \\ \frac{-3}{-15}=0.2 \end{gathered}$

So the dilatation factor is:

$0.2=\frac{1}{5}$
