1 Easy

1 of 1

Application +4 | -1

If the distance of a point

\left(x_1, y_1\right)

from each of the two straight lines, which pass through the origin of coordinates, is

\delta

, then the two lines are given by

View answer and explanation

Correct option: A

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

Option A ((

x_1 y-x y_1)^2=\delta^2(x^2+y^2)

) is correct because it is derived from the distance formula of a point from a line passing through the origin.
