Question

In a 2-dimensional coordinate system, which of these is an example of an object's position?

Answer 1

' B ' is the only choice on the list that tells you a definite place, where you could go to pick up the object or meet somebody.

But in order to use it, you also have to know where the origin of coordinates is ... the point (0, 0) .

__________

No, I'm wrong about that.  You have to know where SOME other point is, but that doesn't have to be (0, 0).
