10. (12, 24)
Step-by-step explanation:
An isometry preserves the orientation of a shape. In other words, nothing will change.
In dilations, a scale factor is how many times the preimage will be increased by. In other words, this is what you multiply the x and y-coordinates by.
For example, in question 4, the image has a dilation of 2.
(3, -2) ⇒ (6, -4).
