Question

You start at (4, 2). you move right 5 units. where do you end?

Answer 1

the answer to this would be (9,2)

Answer 2

when shifted left or right, the x value changes, the y value stays the same.
when moved up and down, the y value changes, the x value stays the same.
in this case, 4+5=9, so the end point is at (9, 2)
