Question

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

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

The correct answer is: $fraction numerator x minus 3 over denominator 1 end fraction equals fraction numerator y minus 2 over denominator 0 end fraction equals fraction numerator z minus 5 over denominator 4 end fraction$

Here P and Q lie on the same side of XY plane
