JEE MainMathematicsToughStraight Lines
If one of the lines of [IMAGE] is a bisector of
the angle between the lines xy = 0, then m is
Show answer and solution
[IMAGE] or [IMAGE] represents two perpendicular lines through
origin
since [IMAGE] or [IMAGE] is one of the
possibility so automatically both are the angle bisectors of xy = 0
Hence (y + x)(y - x) = 0 and [IMAGE] are identical
[IMAGE] which is true and satisfies all equations
