Question

Find the sum using the number line.

Answer 1

D.-3

-12+15=3  hope it helps

Answer 2

Here is your answer:

• Using the number line you will have to start at -12
• $-12$
• Then drawing a line 15 spaces to the right of -12
• Which equals positive 3

You can also find the answer this way:

• $-12 + 15 = 3$
• But they want you to use the number line so the first way is the one you need to take a look at:
• $=3$

Therefore your answer is "3" or the fourth option.

Hope this helps!
