If line `4x-3y=0` coincides with one of the lines `ax^(2)+2hxy+by^(2)=0` then

If the line 4x-5y=0 coincide with one of the lines given by ax^(2)+2hxy+by^(2)=0 , then

If the line 4x+5y=0 coincide with one of the lines given by ax^(2)+2hxy+by^(2)=0 , then

If the line 3x-2y=0 coincide with one of the lines given by ax^(2)+2hxy+by^(2)=0 , then

If the line px +qy =0 coincides with one of the lines given by ax^(2)+2hxty+by^(2)=0 then

If line lx+my+n=0 is perpendicular to one of the lies ax^(2)+2hxy+by^(2)=0 then

If one of the lines represented by the equation ax^(2)+2hxy+by^(2)=0 is coincident with one of the lines represented by a'x^(2)+2h'xy+b'y^(2)=0, then

if one of the lines given by the equation ax^2+2hxy+by^2=0 coincides with one of the lines given by a'x^2+2h'xy+b'y^2=0 and the other lines representted by them be perpendicular , then . (ha'b')/(b'-a')=(h'ab)/(b-a)=1/2sqrt(-a a' b b')
