The lines 2x + y -1=0 , ax+ 3y-3=0 and 3x + 2y -2=0 are concurrent for -

The lines 2x+y-1=0, ax+3y-3=0, 3x+2y-2=0 are cuncurrent

The lines 2x-y-1=0, ax+3y-3=0 and 3x+2y-2=0 are concurrent for

If the pairs of lines x^2+2x y+a y^2=0 and a x^2+2x y+y^2=0 have exactly one line in common, then the joint equation of the other two lines is given by 3x^2+8x y-3y^2=0 3x^2+10 x y+3y^2=0 y^2+2x y-3x^2=0 x^2+2x y-3y^2=0
