Thank you for the opportunity to help you with your question!

In x-y coordinate system a point is represented as (x, y), where x-axis is the horizontal and y-axis is vertical

The point (a, b) means a is x-coordinate and b is y-coordinate

translation 4 units down means b goes to (b-4) and a remains untouched

The coordinates of the image is (a,b-4),

Any vertical translation does not change the x-coordinate.

In the same manner any horizontal translation will not change y-coordinate.

Please let me know if you need any clarification. I'm always happy to answer your questions.
