(a) Find the gradient of each of the lines through the points A and B, and
through the points B and C.
(b) Find the equation of each of the lines through the points A and B,
and through the points B and C.
(c) Find the gradient and equation of the line passing through the points

A and C. Hence, determine x and -intercepts.y
