Answer:
6,15
Explanation:
A dilation is the changing of a size. A scale factor is a proportional number that tells us how much we change a shape.
If the scale factor is over 1, the new image will stretch.
If the scale factor is under 1, the new image will shrink
Since we are asked to find A' (which is prime notation) meaning that we are asked to find the coordinates where A' is at on the new image.
Since the scale factor is 3,
3 is greater than 1 so it will stretch.
Now, multiply 3 to each number
to find it new location.
So the coordinates are at 6,15
