In three-dimensional geometry the equations of the x-axis are given by y = 0 and z = 0 since all points on the x-axis have y and z coordinates equal to zero. In parametric form the x-axis is represented as x = t y = 0 and z = 0 where t is a parameter.
Class 12 Maths Chapter 11 Three Dimensional Geometry is crucial for CBSE Exam 2024-25. It includes concepts such as direction cosines and direction ratios of a line equations of a line in various forms shortest distance between two lines equations of a plane angles between planes and the distance of a point from a plane.

The x-axis in three-dimensional space consists of all points where the y and z coordinates are zero. Therefore, the equations of the x-axis are:
y = 0 and z = 0
In parametric form, the x-axis can be represented as:
x = t, y = 0, and z = 0, where t is a parameter.
So, the correct answer is: α
