In mathematical statements regarding vector quantities we may encounter expressions involving the negative of a vector (that is, minus that vector, or multiplied by a -1 factor). What is the visual or graphical interpretation of such expression?
1. Is a vector that points left.
2. It is a vector that points down.
3. It is a vector that points in a direction opposite to that of the original vector.
4. It is a vector that points in negative direction of the system of coordinates used.
5. This expression makes mathematical sense but does not have a direct geometrical or physical interpretation.

I would say 3 or 4 because usually it is negative to its Origin...I am not sure though.

3. It is a vector that points in a direction opposite to that of the original vector.
Negative of a vector (a vector multiplied by a -1 factor) just means it is in the opposite direction of the original vector.
However, if you minus a vector - say a vector with a magnitude of 5 (pointing east) minus a vector with a magnitude of 4 (pointing east as well) will still result in a vector with a magnitude of 1 in the same direction.
