Show that A (-2, 2 + 3), 2 € Z lies on the line x + y - 3 = 0.
Given that the equation of the perpendicular bisector of AB is 2x - y - 1 = 0, show
that the coordinates of B = (72+16, 7-1)
-
The perpendicular bisector of AC is x + 3y - 23 = 0. Express the coordinates of C in
terms of 1. If the points P = (3,6) lies on BC, find the value of 2. Hence find the
equations of the sides AB, BC and CA of the AABC.
