| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
Correct translation | 2 | B1 for a translation \(\begin{pmatrix} 3 \\ k \end{pmatrix}\) or \(\begin{pmatrix} k \\ -2 \end{pmatrix}\) or three correct points not joined or three joined points and one just out of tolerance | \(k\) can be 0 mark intent (vertices within \(\pm\)2 mm of correct position by eye) Ignore “counting” dots, intermediate position dots and dots on perimeter To be considered for the mark one point would need to be less than half way to the next gridline and the others in tolerance |
