Question

You move right 8 units. You end at (3, 2). Where did you start?

Answer 1

Answer: (-4, 2)

Step-by-step explanation: Start where you end off and move left 8 units to get your starting point

Answer 2

When you move either left or right (horizontally), you’re moving along the x axis.

So there’s a change of 8 in the x axis.

The Y value doesn’t change because you’re not moving up or down

Now since we’re moving right, the values are increasing.

Let’s make the unknown/original starting x coordinate “n”

Original

(n, 2)

New

(3,2)

There’s a change of +8 because it’s moving towards the right.

n+8 = 3

Solve:

N=-5

The original location was

(-5, 2)
