4.A) A straight line L1 whose equation is 3y-2x-2 meets the x-axis at R. Determine the co-ordinates of R byAsecond line l2 is perpendicular to LI at R Find the equation of L2 in the form y=mx+c A Third line l3 passes through (-4,1) and is parallel to LI Find, i) the equation of L3 in the form y=mx+c the co-ordinates of points at which l3 intersects l2.
