Question

you start at (3, -2). you move left 8 units. where do you end?

Explanation:

Step1: Understand coordinate movement

Moving left on a coordinate - plane changes the x - coordinate. Moving left means subtracting from the x - value. The y - coordinate remains the same when moving horizontally.
The starting point is $(3,-2)$. The x - coordinate is 3 and the y - coordinate is - 2.

Step2: Calculate the new x - coordinate

We move 8 units to the left. So we subtract 8 from the x - coordinate of the starting point.
The new x - coordinate is $3−8=-5$. The y - coordinate stays as - 2.

Answer:

$(-5,-2)$
