Answer:
<em>The scale factor is 3</em>
Step-by-step explanation:
<u>Dilations</u>
A dilation is a transformation that produces an image that has the same shape as the original but has a different size.
A dilation is described by the scale factor or constant of dilation and the center of the dilation.
We are given a triangle XYZ of coordinates given in the graph to the left:
X=(-1,1), Y=(-1,4), Z=(-2,1)
It was dilated to triangle X'Y'Z' with coordinates:
X'=(-3,3), Y=(-3,12), Z=(-6,3)
Note each coordinate of the dilated triangle is three times the coordinates of the original triangle, thus the scale factor is 3
