Question

A ray of light along x + 3 y = 3 gets reflected upon reaching X - axis, the equation of the reflected ray is, y = 3 x - 3, 3 y = x - 1, y = x + 3, 3 y = x - 3

MARKS App · Accepted Answer

Let incident ray intersecting Y - axis at B and X - axis at A . ∆ O A B is congruent to ∆ O A B ' Hence O B ' = O B Equation of B ' A : x 3 + y - 1 = 1 or x - 3 y = 3 .
