Answer:
Fifth option
Step-by-step explanation:
- Simplify the solution set, so it now looks like this: -2 < x < 8
- Look for the graph that looks the most like the simplified solution set.
- The fifth option has both numbers that's in the solution set, -2 and 8. Therefore, it is correct. It's also in the order on the number line that the solution set is in, so that's another way I know it's correct.
