Answer:
You moved left by 3.
Explanation:
If you start at a position of -5 on a number line and end up at a position of -8, it means you moved to the left along the number line. In other words, you moved in the direction of smaller numbers (towards the negative direction).
To calculate how many units you moved, you can find the difference between your starting point (-5) and your ending point (-8).
Here's the calculation:
Starting point: -5
Ending point: -8
To find the difference, you subtract the starting point from the ending point:
-8 - (-5) = -8 + 5 = -3
So, you moved 3 units to the left (in the negative direction) along the number line.
