<h3>
Answer: The scale factor is 5 used to create the dilation.</h3>
Step-by-step explanation: We are given original image ABCD.
The coordinates of the image ABCD are
A (1, 2)
B ( 2, 2)
C ( 2, 1)
D ( 1, 1).
And coordinates of dilated image A'B'C'D' are :
A' (5, 10)
B' ( 10, 10)
C' ( 10, 5)
D' ( 5, 5).
We can see that (x,y) --> (5x, 5y) rule is being applied there.
<em>Therefore, each x and y-coordinate is being multiplied by 5.</em>
<h3>Therefore, the scale factor 5 is used to create the dilation.</h3>
