#### Equation of x axis

## What is the equation of X axis in coordinate geometry?

Recall from the lesson on Vertical and Horizontal Lines that the equation for the x-axis is y=0, and the equation for he y-axis is x=0. So in other words, any point on the x-axis has a y coordinate of 0. And any point on the y-axis has an x coordinate of 0.

## What do you mean by X axis?

An x-axis refers to the horizontal plane in a Cartesian coordinate system. A position on a two-dimensional graph can be found by creating perpendicular projections from the x-axis and y-axis. In a two-dimensional system, the first and second coordinates are referred to as the abscissa and the ordinate of P.

## What linear equation represents the X axis?

A linear equation has the form y = mx + b, where M and B are constants. The x-intercept is the point where the line crosses the x-axis. By definition, the y-value of a linear equation when it crosses the x-axis will always be 0, since the x-axis is stationed at y = 0 on a graph.

## What is an example of a Y axis?

One of the three axes of a three-dimensional Cartesian coordinate system. The y-axis is the vertical axis in a graph. An example of an y-axis is the axis that runs up and down on a graph. The vertical (V), or nearest vertical, plane on a two- or three-dimensional grid, chart, or graph in a Cartesian coordinate system.

## What is the Y intercept formula?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

## What is y axis on a graph?

more The line on a graph that runs vertically (up-down) through zero. It is used as a reference line so you can measure from it. See: Coordinates.
