If you wanted, you could find the magnitude of this vector displacement with a value of 3.61 meters. You could also find the "direction" of this vector and say that it is 33.7° below the x-axis.

The magnitude of a vector has to be a positive number. To really use these, you need unit vectors. This is what they look like: The little ^ over the x means that it is a unit vector.
