The diagram displays the points $O$ and $R$, together with the vectors $\mathbf{a}$ and $\mathbf{b}$.
(a)[1]
Since $\overrightarrow{OP} = 2\mathbf{a}$, indicate and label the location of $P$ on the grid.
(b)[1]
Since $\overrightarrow{OQ} = 2\mathbf{b} - \mathbf{a}$, indicate and label the location of $Q$ on the grid.
(c)[2]
Write $\overrightarrow{OR}$ using $\mathbf{a}$ and $\mathbf{b}$.
