b. (+5) + (-7) = - 2 matches the number line graphic, since +5 is at +5 to the right and by - 7, we need to go backwards through 7 numbers. That brings us to - 2.
Others are not algebraically correct.

B is the only answer above which is mathematically correct.
But your question about matching the number line graphic.... a graphic is the picture that you are looking at. I attached a link that shows you a "number line". Only you can see the graphic that the question is about.

I'm guessing "b" because it's the only correct one.

answer b
it is the only correct one because the other ones don't add up.
