Question

you start at (5, -5). you move left 8 units. where do you end?

Explanation:

Step1: Recall coordinate - movement rule

Moving left on the x - axis changes the x - coordinate. Moving left means subtracting from the x - coordinate. The y - coordinate remains the same when moving horizontally.
The starting point is $(5,-5)$. The x - coordinate is 5 and we move 8 units left.

Step2: Calculate the new x - coordinate

New x - coordinate = Initial x - coordinate - 8. So, $5−8=-3$. The y - coordinate stays as $- 5$.

Answer:

$(-3,-5)$
