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
. The point
does not lie on the reflected ray.

Without a diagram or any given information about the angle of incidence or the position of the point, it is impossible to determine the equation of the reflected ray or its relationship to point . Please provide more information or a diagram for further assistance.
