X-Axis Definition

It is one axis from two dimensional or three-dimensional graph or space in which you want to display the location of any object. The X-Axis is the horizontal line that moves in the right and left directions from the Origin (The point where all axis intersects) of the plane.

The x-axis gives the value of any object distance from the origin of the plane. It shows how far an object has been moved from the point of origin on the horizontal axis. It can be positive or negative in both directions as per the requirements of the problem.

Significance of x-axis

This axis and its belonging axis have great importance for students dealing with different Mathematical fields. It is good to know how to draw the x-axis along with others to learn how to draw a graph for any question.

Here are some of the fields and conditions when you have to deal with this type of problem.

  • Physics
  • Object location
  • To show relationship between two quantities
  • Basic to advanced Mathematics problems

Other types of axis

There are two major axes in a two-dimensional framework or plane. These are termed the x-axis and y-axis. We have discussed the first one in detail in the above sections. A y-axis is a perpendicular plane to the x-axis that also originates from the Origin where all values are “0”.

In the case of three-dimensional space, another axis involves the above two and is termed the z-axis. This axis is perpendicular to both the above-mentioned axes. Normally, it is considered an imaginary axis because we can’t draw a three-dimensional shape on the paper as it is two-dimensional only.

Which axes are involved in a two-dimensional plane?

In the two-dimensional plane, the x-axis and y-axis are involved only.

What is its origin?

It is the point of intersection where all axis meets with each other.

Why all values are zero at the origin?

All values are zero at the origin because all axis are considered to originate from that point.

Why z-axis is considered imaginary normally?

It is because we can’t draw this axis normally on our two-dimensional paper. That is why we consider it to be an imaginary axis in space that we can’t see or draw but understand.
