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

Equation of a line passing through (x1, y1, z1) and parallel to a line with direction ratios a,b,c is


Since the line passes through origin i.e. (0,0,0)


x1 = 0, y1 = 0, z1 = 0


Since line is parallel to x - axis,


a = 1, b = 0, c = 0


Equation of Line is given by –
