Do the ordered pairs below represent a relation, a function, both a relation and a function, or neither a relation or function? (-1,-1),(3,-9),(6,-15),(9,-21)

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 it’s d as the answer.
