For the lines `L_1: 3x - 2y +5=0 and L_2 : kx + by – 15 = 0` ` L_1` is perpendicular to `L_2` if `k=4`.

Consider the lines give by L_1: x+3y -5=0, L_2:3x - ky-1=0, L_3: 5x +2y -12=0

Consider the lines given by L_1 : x+3y-5=0, L_2 : 3x-ky-1=0 and L_3 : 5x+2y-12=0 .one of L1,L2,L3 is parallel to at least one of the other two, if k=

If points (h,k) (1,2) and (-3, 4) lie on line L_(1) and points (h,k) and (4,3) lie on L_(2). If L_(2) is perpendicular to L_(1), then value of (h)/(k) is

Let L be the line joing the origin to the point of interesection of the lines represecnted by 2x^(2)-3xy-2y^(2)+10x+5y=0 . If L is perpendicular to the line kx+y+3=0, then k=

Let L be the line joining the origin to the point of intersection of the lines represented by 2x^(2)-3xy-2y^(2)+10x+5y=0 . If L is perpendicular to the line kx+y+3=0 then k=
