For this case we have the following transformation:

Using the transformation we have that the image is:

Therefore, making use of this information, we can find the coordinates of the pre-image
We have then:

From here, we clear x:

On the other hand we have:

From here, we clear y:

The coordinates of the pre-image is:
Answer:
A point that is the pre-image is:
