X and Y Axis
x and yaxis are two important lines that make a graph. A graph consists of a horizontal axis and a vertical axis where data can be represented. A point can be described in a horizontal way or a vertical way, which can be easily understood using a graph. These horizontal and vertical lines or axis in a graph are the xaxis and yaxis respectively. In this minilesson, we will learn about the xaxis and yaxis and what is x and yaxis in geometry along with solving a few examples.

X and YAxis Definition
Any point on the coordinate plane is well defined by an ordered pair where the ordered pair is written as (xcoordinate,ycoordinate) or (x,y), where xcoordinate represents a point on the xaxis or perpendicular distance from the yaxis and ycoordinate represents a point on the yaxis or perpendicular distance from the xaxis. X and yaxis are the axes used in coordinate systems that form a coordinate plane. The horizontal axis is represented by the xaxis and the vertical axis is represented by the yaxis. The point where the x and yaxis intersect is known as the origin and is used as the reference point for the plane. The xaxis is also known as abscissa or x graph whereas the yaxis is also known as ordinate or y graph. The image below shows the respective representation.
For example: The population of a city from 2015 to 2020 is given in the X and Y graph table as:
Years  2015  2016  2017  2018  2019  2020

To locate any point on the coordinate plane, we use an ordered pair where the ordered pair is written as (xcoordinate,ycoordinate) or (x, y), where xcoordinate represents a point on the xaxis or perpendicular distance from the yaxis and ycoordinate represents a point on the yaxis or perpendicular distance from the xaxis, therefore it is clear from above that xaxis comes first when writing the ordered pair to locate a point. We can see here that the location of each point on the graph is noted as an ordered pair where the xaxis or xcoordinate leads the yaxis or ycoordinate. Then to represent these points on the x and y chart, using years on the xaxis and the corresponding population on the yaxis as:
X and YAxis Equation
Let's consider a linear equation y = 2x+1. Now to graph this equation construct a table having two columns for values of x and y. To draw the x and yaxis coordinate graph of the linear equation, we need to draw the X and Yaxis grid table for at least two points.

Now draw the points on the graph where the values of x lie on xaxis and the corresponding values of y lie on yaxis. Then join the points with a straight line to draw the graph of the equation.

Important Notes:
 xaxis is also called abscissa.
 y axis is also called ordinate.
 There are infinite points on the xaxis and yaxis.
 Origin is the intersection point of xaxis and yaxis.

X and Y Axis Examples

Example 1: Daniel is given an x and yaxis math problem by his teacher, where he has to plot the points (3,2) and (2,3) on a graph and draw a line passing through these points. Can you determine the point where it meets xaxis?
Solution: The points can be plotted on the graph as shown.
Therefore, the line meets the xaxis at the point (5,0).

Example 2: Plot the points (0,2), (0,4.5), and (0,3) on a coordinate system. Do all the points lie on a line? Can you name the line?
Solution: The points on the graph are shown below.
Clearly, the points lie on a line on the y axis.
FAQs on X and Y Axis
What are the 4 Quadrants in a Graph?
The four quadrants or x and yaxis quadrants are as follows:
 Quadrant 1: Is the positive side of both x and y axis.
 Quadrant 2: Is the negative side of x axis and positive side of y axis.
 Quadrant 3: Is the negative side of both x and y axis.

How Do I Graph an Equation?
To graph an equation, first construct a table having two columns for values of x and y. Then draw the points on the graph where the values of x lie on the xaxis and the corresponding values of y lie on the yaxis. Then join the points to draw the graph of the equation.
Which Point is on the Negative yaxis?
The point which has a negative value of its ycoordinate is on the negative yaxis.
Which is x and yaxis?
The horizontal axis is known as the xaxis and the vertical axis is known as the yaxis.
How Do you Plot a Graph with the x and yaxis?
At first, we draw and label the x and yaxis. Then we plot the coordinates of the function at various values of the x and ycoordinates. Then we connect the coordinates and plot the graph of a function.
What is the Name of the yaxis?

What is the Name of the xaxis?
The xaxis is known as the ordinateaxis.
