Question 88188: A vector has the following initial and terminal points respectively:
initial point (-1,2)
terminal point (4,6)
What is the position vector?

If you want to find the vector from the point (-1,2) to (4,6), simply subtract the vector from like this.



So the position vector is



Notice how when we subtract vectors, the resulting vector is a vector from the tip of the first vector to the tip of the second one. To prove that is the position vector, simply shift the resulting vector to have an initial point at (0,0) (the shifted vector is shown in green). Here you can see that the shifted vector has a terminal point at (5,4). This verifies our answer

Plot of , , and the resulting vector . Notice how the shifted vector is equivalent to the position vector.
