1. The equation 
represents a pair of straight lines if 
2. 
3. Let 
be the slopes of the lines 
. Then,
But 
(given). Therefore,
and 
,
i.e.,
. Also, 
4. Equation of the bisectors of the angle between the lines 
is
or 
Which is same as the equation of the bisector of angles between the lines 
Thus, the two line pairs are equally inclined to each other for any value of
