Vector coordinates and its points

    Is there a way to know the points if I only have the vector coordinates and I can't use the origin as one of the points? For example, if I have vec(PQ) <-1,4,-5> . Is there a way to know the points of this vector?

    Do you mean, is there a way to find P and Q? No.

    Do you understand that a vector does NOT have specific "points"? A basic property of a vector is that two different "directed line segments" (for example, the segment from (1, 1, 1) to (0, 5, -4) and the segment from (3, 1, 2) to (2, 4, -3)) can represent the same vector and have no "points" in common.
