Triangle S has vertices at A(1, 2), B(1, 6) and C(4, 2).
Figure (to be drawn): A coordinate grid (0 to 8 on both axes) with triangle S plotted using vertices A(1, 2), B(1, 6) and C(4, 2).
(a)Write the coordinates of the image of vertex C after a reflection in the y-axis.(1)
(b)Work out the area of triangle S.
You may get a mark for using a correct method even if your answer is incorrect.(2)
