Points A and B have co-ordinates (3, 4) and (0, 2) respectively. Find the image :
(a) A' of A under reflection in the x-axis.
(b) B' of B under reflection in the line AA".
(c) A" of A under reflection in the y-axis.
(d) B" of B under reflection in the line AA".
The image of the point (1, 5) when reflected in a line LM is (9, 5). Write down the equation of the line LM.
