| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Rotation | 1 | More than 1 transformation scores 0 A vector alone does not imply translation but does with “and then...” Do not accept turn oe for rotation | |
| [centre] (0, 2) | 1 | Condone missing brackets; do not accept \(\begin{pmatrix} 0 \\ 2 \end{pmatrix}\) for (0, 2) | |
| 180˚ | 1 | Allow if accurate point plotted (½ square) and referred to Ignore direction | |
