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.

\(\frac{-18}{-4}\)   \(\frac{36}{8}\)

to get

\(4.5\) \(4.5\)

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.
