| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(\begin{pmatrix} 7 \\ 3 \end{pmatrix}\) | 2 | M1 for \(\overrightarrow{\mathrm{PQ}} + \overrightarrow{\mathrm{QR}}\) or \(\begin{pmatrix} 3 \\ 2 \end{pmatrix} + \begin{pmatrix} 4 \\ 1 \end{pmatrix}\) or B1 for answer \(\begin{pmatrix} 7 \\ k \end{pmatrix}\) or \(\begin{pmatrix} k \\ 3 \end{pmatrix}\) | M1 If fraction line in final answer For M1 allow 3 + 4 and 2 + 1 |
