Answer 2

Sum = -1 on the number line.

Explanation:

As you are given a number line, you will see the markers labeled with possible answers. You start from zero, as if you have no value at all. Then you follow the rules of pemdas and begin moving to the right of the number line by positive 3 points. Then, you do as the equation asks and subtract (go backwards; move to the left) 4 points. Returning 4 spaces and going past the zero mark into the negatives. Finding your answer at the point of negative one.
