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
A. y - x = 6
B. y + x = 6
C. -y + x = 6
D. y + x = 5
E. y - x = 5
The point
(2, 4)
(4, 2)
(8, -2)
(-2, -8)
does not lie on the reflected ray.
