Shape A can be transformed to shape B by a reflection in the \(x\)-axis followed by a translation \(\begin{pmatrix} c \\ d \end{pmatrix}\)
Find the value of \(c\) and the value of \(d\). (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(c = -6\) \(d = -1\) | M1 | for reflection in \(x\)-axis shown on diagram |
| A1 | for \(c = -6\) or \(d = -1\) | |
| A1 | for both \(c = -6\) and \(d = -1\) | |
| SC B2 for \(c = -1\) and \(d = -6\) |
Additional guidance
Vertices (3, −2), (5, −2), (3, −5)
One correct value is M1A1 regardless of second value or diagram
