Answers (1)

Answer: the equation parallel to x-axis will be \frac{x}{1}=\frac{y}{0}=\frac{3}{0}

Given: find the equation of the line parallel to x-axis and passing through the origin

Hint: the line parallel to x-axis so the direction ratio will be (1,0,0);(0,1,0);(0,0,1)

Solution:

                Equation:

                            \begin{aligned} &\frac{x-x_{1}}{a}=\frac{y-y_{1}}{b}=\frac{z-z_{1}}{c} \\ &\frac{x-0}{1}=\frac{y-0}{0}=\frac{z-0}{0} \\ &\frac{x}{1}=\frac{y}{0}=\frac{z}{0} \end{aligned}

So the equation will be =\frac{x}{1}=\frac{y}{0}=\frac{z}{0}
