18. The diagram shows triangle \(A\).

(a) Reflect triangle A in the line \(y = 4\).
Label your answer \(B\). [2]

(b) Translate triangle A using the vector \(\begin{pmatrix} 6 \\ 0 \end{pmatrix}\).
Label your answer \(C\). [2]

Mark scheme (a)

Scheme	Marks	Comments
Correct triangle with coordinates: (\(-1\), 4), (\(-6\), 3), (\(-3\), 1)	B2	B1 for: 3 points correctly plotted but not joined, a triangle with 2 points correctly plotted, a correct reflection in \(y = k\), \(k \neq 4\).

Mark scheme (b)

Scheme	Marks	Comments
Correct triangle with coordinates (5, 4), (0, 5), (3, 7)	B2	B1 for: 3 points correctly plotted but not joined, a triangle with 2 points correctly plotted, a translation \(\begin{pmatrix} 6 \\ m \end{pmatrix}\), \(m \neq 0\), a translation \(\begin{pmatrix} n \\ 0 \end{pmatrix}\), \(n \neq 6\), a translation \(\begin{pmatrix} 0 \\ 6 \end{pmatrix}\). Treat translation of triangle \(B\) as a misread and award B1 for (5, 4) (0, 3) (3, 1). FT ‘their triangle \(B\)’.
