Question

You start at (8, 3). You move down 1 unit. Where do you end?

Answer 1

• (8, 2)

Explanation:

Initial point is: (x, y) = (8, 3)

• When you move up or down, you change the y-coordinate
• When you move left or right you change the x-coordinate

Move down 1 unit:

• (x, y) → (x, y - 1)

The new point is:

• (8, 2)
