Solution

$Equation of x - axis is symmetric form is \frac{x - x_{1}}{a} = \frac{y - y_{1}}{b} = \frac{z - z_{1}}{c} where (x_{1}, y_{1}, z_{1}) = (0, 0, 0) [since x - axis passes through origin] and (a, b, c) = (1, 0, 0) i . e . direction ratios of x - axis (1, 0, 0) ∴ Equation of x - axis in symmetric form is \frac{x - 0}{1} = \frac{y - 0}{0} = \frac{z - 0}{0}$
