Answer:
2
Step-by-step explanation:
so you start at 5 right
then you subtract 7 from 5, or in the case of the number line, move 7 lines to the left
then, when you subtract a negative, you actually add the number
so when it says -(-4) it actually goes +4, so you move 4 lines to the right
that places you on the line that says 2
so the answer is 2
