The blue shape is a dilation of the black shape. What is the scale factor of the dilation?

Step-by-step explanation:

We are going to evaluate a vertex of both forms.

blue shape:

(-5.10)

black shape:

(-1,2)

As one figure is the dilatation of another then:

k (-1,2) = (- 5,10)

From here we know:

-k = -5

Equivalently:

2k = 10

Where we conclude:

k = 5

The scale factor of the dilation is:

k = 5
