Which number line shows point A at -2 , point B at 3.5, point C at -3 1/2 , and point R which is the opposite of point A

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

Ithink the answer may be -7 by when dividing both sides by -3
