If the distance of two lines passing through origin from the point

\left(x_1, y_1\right)

is '

d

', then the equation of lines is

View answer and explanation

Correct option: A

\left(x y_1-y x_1\right)^2=d^2\left(x^2+y^2\right)

Option A ((

x y_1-y x_1)^2=d^2(x^2+y^2)

) is correct because it represents the equation of the pair of lines passing through the origin, given the distance 'd' from the point (x1, y1).
