Given: point A= (1, 4) and point A’= (-3, -1)

Since the points have been moved, hence the transformation used here is Translation!

The ‘x’ coordinate has changed from 1 to -3 =>change= 1– (-3) = 4 units to the left.

The ‘y’ coordinate has changed from 4 to -1==> change= 4– (-1) = 5 units down.

Given: object side length = 6 units

Image side length = 18 units.

Here, clearly the size of the object has been changed since the length of the object is changed.

Therefore the transformation used here is Dilation.

Scale factor = (Image length) / (Object length) = 18/6 = 3

This implies that the object has been enlarged by a scale factor of 3!
