Find the equation of a line parallel to x-axis and passing through the origin.

Question

$\begin{array}{1 1} \large\frac{x-1}{1}=\large\frac{y}{0}=\large\frac{z}{0} \\ \large\frac{x}{0}=\large\frac{y}{1}=\large\frac{z}{1} \\ \large\frac{x}{1}=\large\frac{y}{0}=\large\frac{z}{0} \\ \large\frac{x}{1}=\large\frac{y}{1}=\large\frac{z}{0} \end{array} $
