Question
1. (a) Find the angle through which the axes are to be turned so that the equation
V3x + y - 4 = 0 may be reduced to the form x = k. Also, determine the value of k.
(b) Show that the equation x² +4.xy – 2 y +6x – 12 y – 15 = 0 represents a pair of
straight lines which together with x² +4xy - 2 y² =0 form a rhombus.
