Problem

A ray of light is sent through the point

P(1, 2, 3)

and is reflected on the

XY

-plane. If the reflected ray passes through the point

Q(3, 2, 5)

, then the equation of the reflected ray is (1)

\frac{x-3}{1} = \frac{y-2}{0} = \frac{z-5}{1}

(2)

\frac{x-3}{1} = \frac{y-2}{0} = \frac{z-5}{-4}

(3)

\frac{x-3}{1} = \frac{y-2}{0} = \frac{z-5}{4}

(4)

\frac{x-1}{1} = \frac{y-2}{0} = \frac{z-3}{4}
