Answer:
This isn't really that hard to solve.
Explanation:
For the first one (H): 3 units to the left of 0.
This has to mean that our integer will be negative, and thus, -3 should be written. To the right of 0 would mean it's positive. So, you would find the spot for -3 on the number line and write the letter "H."
The last one (H): not positive or negative.
This means that the integer would have to be 0, as it satisfies the condition that the integer is neither positive (+) nor negative (-). So, you would find the spot marked 0 on the number line and write the letter "H."
If you have any more questions, I would be happy to help, but, personally, this seems like a straightforward assignment.
