Question

can anyone help me how to find vector of AB if given A=(-2,1)and B=(1,4)?

Answer 1

move A to the origin, and move B to suit

Answer 2

whatever you do to move one point, move the other by the same

A=(-2,1) and B=(1,4)
+2 -1 +2 -1
----------------------
0 0 3 3

now the vector from A to B is the same as the vector for the origin to B'

Answer 3

in mathing circles ... this is known as B-A

Answer 4

oh ok thanks..
