a).A straight line L1 whose equation is 3y -2x = -2 meets the x-axis at R. Determine the co-ordinates of R. (2 marks) (b) A second line L2 is perpendicular to L] at R. Find the equation of L2 in the form y = mx + c, where m and c are constants. (3 marks) (c) A third line L3 passes through (-4, 1) and is parallel to Ll. Find:
(i) The equation of L3 in the form y = mx + c, where m and c are constants. (2 marks) (ii) The co-ordinates of point S, at which L3 intersects L2. (3 marks)
