Application +4 | -1
If r(1−m2)+m(p−q)=0r\left(1-m^2\right)+m(p-q)=0, then a bisector of the angle between the lines represented by the equation px2−2rxy+qy2=0p x^2-2 r x y+q y^2=0, is
View answer and explanation
Correct option: C
y=mxy=m x
Option C, y=mxy=mx, is correct because substituting this equation into the bisector equation leads to the given condition.
