in the sketch below, the coordinates of the vertices of triangle ABC are A(2:1), B(-2:-3) and C(-4:3) with D(-1: 2) on AC and E(-3;0) on BC. C4.3) 0-1:2 E 3.0) 1-2-3 1.1 Calculate the gradients of AB and DE. 1.2 What can you deduce about lines AB and DE? Give a reason for your answer.

Which equation represents the line that passes through the points and (4, 10) and (2, 7)? y = 3/2x - 11y = 3/2x +4y = - 3/2x + 19y = - 3/2x + 16
