Answer:
Answer choice b. is correct. You have it right.
Explanation:
You go left 2 because of the negative sign. Since you are subtracting a negative number, you add the opposite, so you add 4.

-2+4
2
I believe the one you selected is correct. A negative plus a negative makes a positive meaning you start at -2 and end with +2
