Which problem is modeled on the number line?

a. 3 + (-6)
b. -3 + (-6)
c. 3 + 6
d. -3 + 6

The answer is d -3+6. D is the correct answer because the number line shows the arrow moving 3 spaces left from 0 which is -3, then the number line shows the arrow moving 6 spaces from -3 which represents addition.

I hope this answer was helpful.
