Answer:
8 units
Step-by-step explanation:
Since the y-coordinates are the same, you are only traveling horizontally, or from left to right. Therefore, you can find the length of the segment using a number line (like the one attached!) From -3 to 0 is 3 units, and from 0 to 5 is 5 units. Since 3 + 5 is 8, the segment is 8 units long.
