The line

y=m x

bisects the angle between the lines

a x^2+2 h x y+b y^2=0,

View answer and explanation

Correct option: B

h\left(m^2-1\right)+m(a-b)=0

Option B (

h\left(m^2-1\right)+m(a-b)=0

) is correct because it represents the condition for the line

y=mx

to bisect the angle between the lines

a x^2+2 h x y+b y^2=0
