A ray of light is reflected from a mirror such that the reflected ray is perpendicular to the original ray, as shown in the diagram.



The equation of the reflected ray is

Ay - x = 6

By + x = 6

C-y + x = 6

Dy + x = 5

Ey - x = 5

The point

(2, 4)

(4, 2)

(8, -2)

(-2, -8)

does not lie on the reflected ray.
