Point A is the pre-image of a vertex of a square and is located at (–10, 8). The square is dilated with the center of dilation at the origin. Point A’ is the image and is located at (–7.5, 6). What is the scale factor of the dilation?

To find the scale factor of the dilation, divide the new point's x and y values by the original point's x and y values:

[tex]-7.5 \div -10 = 0.75[/tex]
[tex]6 \div 8 = 0.75[/tex]

The scale factor of the dilation is 0.75.

Answer: Person above me is right but imma put my answer anyways: its 0.75

Step-by-step explanation:

-7.5/-10 = 0.75

6/8 =0.75

If you ever forget how to do this take the coordinates of A' and divide them by the coordinates of A. (or whatever letter is used in the problem)
