A relation is a set

kewlgeek555 · Answer

But I am not very sure about the whole "set of points"

kewlgeek555 · Answer

So it could be a set of points?

zzr0ck3r · Answer

you are correct

zzr0ck3r · Answer

yes but there is no reason that MUST be (x,y)

zzr0ck3r · Answer

I think you are asking why it is not d?

kewlgeek555 · Answer

Oh, okay.  Just wanted to clarify.  I know why it can't be D, because relations can be represented in several ways including on a coordinate plane, mapping, x/y graph.

I was just confused because I know a relation can be a set, but I didn't know if it was necessarily a set all the time or if it is a set of points.  Thanks @zzr0ck3r
