Foundation June 2023 Paper 2 Q20
20 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 \(\begin{pmatrix}4\\-3\end{pmatrix}\) eg2 4 right 3 up and \(\begin{pmatrix}4\\3\end{pmatrix}\) eg3 4 right 3 down eg4 Rotate 4 left and 3 up and \(\begin{pmatrix}-4\\3\end{pmatrix}\) | B2 B1 B0 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 \(\begin{pmatrix}\text{4 right}\\\text{3 down}\end{pmatrix}\) or \(\begin{pmatrix}\text{4 r}\\\text{3 d}\end{pmatrix}\) or \(\begin{pmatrix}4 \rightarrow\\3 \downarrow\end{pmatrix}\) | B0 |
