Reflected light A ray of light comes in along the line from the second quadrant and reflects off the x-axis (see the accompanying figure). The angle of incidence is equal to the angle of reflection. Write an equation for the line along which the departing light travels.

The path of the light ray in Exercise 44. Angles of incidence and reflection are measured from the perpendicular.
