Position vectors are vectors giving the position of a point relative to the origin (\(O\)).
A point \(A\) with coordinates \((x,y)\) has the position vector \(\overrightarrow{OA} \).
\(\overrightarrow{OA} = x\bold{i} + y\bold{j} = \begin{pmatrix} x \\ y \end{pmatrix} \)
\(\overrightarrow{AB} = \overrightarrow{OB} - \overrightarrow{OA} \)
