Let L be the line passing through the point P(1,2) such that its intercepted segment between the co-ordinate axes is bisected at P. If L1 is the line perpendicular to L and passing through the point (−2,1), then the point of intersection of L and L1 is :
(4/5,12/5)
(11/20,29/10)
(3/10,17/5)
(3/5,23/10)
