Shape drawn at (0, 7), (–4, 9), (–6, 5), (–2, 5) [1]
= 2
B1 for reflection in x = k or in y = 1 Note: reflection in y 1 has coordinates (2, –5), (4, –3), (8, –3), (6, –7). or for three correct vertices
17(b)[3]
Enlargement 1 − 2 (2, –1) [3]
B1 for each Do not allow dilation or reduction. If more than one transformation, award 0 marks. Treat extra properties as choice. −and ‘origin 2, 1 −’. Condone 2, 1 Do not treat centre as a column vector as an additional transformation.
