Questions
The straight lines represented by the equation are equally inclined to the line
a
x−2y=7
b
x+2y=7
c
x−2y=4
d
3x+2y=4
detailed solution
Correct option is B
The given pair of lines is 135x2−136xy+33y2=0________(1)The equation of bisectors of angles between the pair of lines (1) isx2−y2a−b=xyh or x2−y2135−33=xy−68or 2x2+3xy−2y2=0 or (x+2)(2x−y)=0one of the bisectors is x+2y=0 which is parallel to the linex+2y=7Hence, the line x+2y=7is equally inclined to the given lines.Talk to our academic expert!
