## a line L is drawn from P(4,3) to meet the lines L1: 3x+4y+5=0 and L2:3x+4y+15=0 at point A and B respectively. From A a line perpendicular to L is drawn meeting the line L2 at P. Similarly from B a line perpendicular to L is drawn meeting the line L2 at Q. Thus a paralleogram APBQ is formed. Find the equation(s) of L so that the area of the parallelogram APBQ is least.
