Here is your answer:
- Using the number line you will have to start at -12
- [tex]-12[/tex]
- Then drawing a line 15 spaces to the right of -12
- Which equals positive 3
You can also find the answer this way:
- [tex]-12 + 15 = 3[/tex]
- But they want you to use the number line so the first way is the one you need to take a look at:
- [tex]=3[/tex]
Therefore your answer is "3" or the fourth option.
Hope this helps!
