Answer:

4.5

Step-by-step explanation:

You have to divide the x of the dilation image by the x of the pre-image to get our answer and to double-check, you can also do that to the y value.

[tex]\frac{-18}{-4}[/tex]   [tex]\frac{36}{8}[/tex]

to get

[tex]4.5[/tex] [tex]4.5[/tex]

To make sure you are right, you can multiply the pre-image point by 4.5 and it will get you your image.

Hope this helps.
