Higher June 2023 Paper 2 Q10
10 Write down the translation vector that maps shape A onto shape B. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(\begin{pmatrix} 4 \\ -3 \end{pmatrix}\) | B2 | B1 \(\begin{pmatrix} 4 \\ \ldots \end{pmatrix}\) or \(\begin{pmatrix} \ldots \\ -3 \end{pmatrix}\) SC1 \(\begin{pmatrix} -4 \\ 3 \end{pmatrix}\) |
Additional guidance
| \((4, -3)\) or \(\begin{pmatrix} -3 \\ 4 \end{pmatrix}\) | B0 |
| Ignore words if a vector is also seen | |
| eg1 Reflection \(\begin{pmatrix} 4 \\ -3 \end{pmatrix}\) | B2 |
| eg2 4 right 3 up and \(\begin{pmatrix} 4 \\ 3 \end{pmatrix}\) | B1 |
| eg3 4 right 3 down | B0 |
| eg4 Rotate 4 left and 3 up and \(\begin{pmatrix} -4 \\ 3 \end{pmatrix}\) | SC1 |
| Condone any type of brackets | |
| Condone missing brackets for B2 or B1 or SC1 but must have two numbers in a column | |
| Condone ‘fraction line’ for B2 or B1 or SC1 but must have two numbers in a column | |
| \(\begin{pmatrix} 4x \\ -3y \end{pmatrix}\) or \(\begin{pmatrix} x4 \\ -y3 \end{pmatrix}\) or \(\begin{pmatrix} x + 4 \\ y - 3 \end{pmatrix}\) or \(\begin{pmatrix} 4\text{ right} \\ 3\text{ down} \end{pmatrix}\) or \(\begin{pmatrix} 4\text{ r} \\ 3\text{ d} \end{pmatrix}\) or \(\begin{pmatrix} 4 \rightarrow \\ 3 \downarrow \end{pmatrix}\) | B0 |
