! Will Mark brainliest if correct.

Answer:
its -1/2 or -2
Step-by-step explanation:
because it affects the image, (pre- image means before because of the prefix pre)
the pre image stretches from 2 - 14
and the image is dilated to 1 - 7
so i think its -1/2 since its being taken away from.
and if thats wrong then its -2
