# Write Down the Equation Of x axis

## Question: Write down the equation of x-axis.

x-axis is the axes used in coordinate systems.

## Answer: The equation of x-axis is y = 0.

The horizontal axis in a coordinate plane is represented by the x-axis.

## Explanation:

The points on the x-axis are of the form (a, 0), where a is any real number.

So, the y-coordinate of the point of the x-axis is 0.

The x-axis is represented by the equation y = 0

### Therefore, the equation of x-axis is y = 0.
