Let's say you got a vector, v = (1, 1)

We also have a point, p, at (2, 1). (This will be the tail of our vectors).

Then you got points X, Y, and Z (unknown points), which will be the head of our vectors.

Lets says that: 

Vectors AX = v, AY = -v, and AZ = 2v. What are points X, Y, and Z. 

 

I got: X: (3, 2) Y: (1, 0) and Z: (4, 3). Though I feel confident with my answer, I would just like to confirm with anyone else to make sure I got it right.

But are the coordinates of A given?

Hey Max, sorry for the confusion, I accidentally called the point (2, 1), P instead of A. I meant...
