# X and Y Graph

X and Y Graph

The teacher drew a point on the blackboard and asked her students to identify it.

There were several responses from the students. Do you think these statements can fix the location of the point?

A point can be described in a horizontal way or a vertical way, which can be easily understood using a graph.

In this mini-lesson, we will explore the world of X and Y graph in math. You will get to learn about the X and Y graph table, X and Y graph examples, X and Y graph chart, X and Y graph calculator, and other interesting facts around the topic.

You can try your hand at solving a few interesting practice questions at the end of the page.

## Which Is X-axis and Which Is Y-axis?

X-axis and Y-axis are the axes used in coordinate systems.

They form a coordinate plane.

Look at the coordinate plane shown below. The horizontal axis is represented by the x-axis and the vertical axis is represented by the y-axis.

This is also known as the x and y-axis graph.

## What Does X-axis & Y-axis Represent?

The point where the X and Y-axis intersect is known as the origin and is used as the reference point for the plane.

• The X-axis is also known as abscissa.
• The Y-axis is also known as ordinate.
• Any point on the coordinate plane is well defined by an ordered pair where the ordered pair is written as (x-coordinate,y-coordinate) or (x,y), where x-coordinate represents a point on the x-axis or perpendicular distance from the y-axis and y-coordinate represents a point on the y-axis or perpendicular distance from the x-axis.

X and Y-axis definition can be well understood by the following image: This is also known as the x and y-axis graph chart.

For example, the population of a city from 2015 to 2020 is given in the X and Y graph table as:

 Years People in millions 2015 2016 2017 2018 2019 2020 1 1.5 2 2.5 3 3.5

To locate any point on the coordinate plane, we use an ordered pair where the ordered pair is written as (x-coordinate,y-coordinate) or (x,y), where x-coordinate represents a point on the x-axis or perpendicular distance from the y-axis and y-coordinate represents a point on the y-axis or perpendicular distance from the x-axis, therefore it is clear from above that x-axis 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 x-axis or x-coordinate leads the y-axis or y-coordinate.

Then to represent these points on the X and Y chart, using years on $$X$$-axis and the corresponding population on $$Y$$-axis as: ## How Do You Graph an Equation With X-axis & Y-axis?

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 y-axis coordinate graph of the linear equation, we need to draw the X and Y-axis grid table for at least two points.

$$x$$ $$y$$
0 1
1 3
2 5

Now draw the points on the graph where the values of $$x$$ lie on $$X$$-axis and the corresponding values of $$y$$ lie on $$Y$$-axis.

Then join the points with a straight line to draw the graph of the equation. X and Y graph calculator

Let's try the simulation given below and see the various graphs of the linear equations.

To get the graph, input the two points and click on the draw button.

## What Is the Equation of Y-axis?

Y-axis is the line where the values of $$x$$-coordinate is zero for all the values of $$y$$.

Then the data points for the Y-axis are: $$(-1,0),\;(0.5,0),\;(1.0),\;(1.5,0),...$$

Therefore the equation of the Y-axis is $$x=0$$ and its graph on the X and Y graph chart is shown below. The blue color line is the graph of the Y-axis and its equation is $$x=0$$. Think Tank
1. Can you predict the equation of $$x$$-axis?
2. Sam's age is 2 less than twice the age of his brother James. The age of James is $$x$$ years and the age of Sam is $$y$$ years.
Can you draw the graph of the equation of Sam's age on the X and Y graph chart?

## Solved Examples

 Example 1

Daniel is given an x and y-axis 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 $$x$$ axis?

Solution

The points can be plotted on the graph as shown. The line meets the $$x$$-axis at the point (5,0).

 $$\therefore$$ The required point is (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.

All the points lie on $$y$$- axis.

 $$\therefore$$ The given points lie on $$y$$- axis.

### 1.  What are the 4 quadrants in a graph? ### 2. 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 x-axis and the corresponding values of $$y$$ lie on the y-axis. Then join the points to draw the graph of the equation.

### 3. Which point is on the negative $$y$$-axis?

The point which has a negative value of its $$y$$-coordinate is on the negative $$y$$-axis.

### 4. Which is x-axis and which is the y-axis?

The horizontal axis is known as the x-axis and the vertical axis is known as the y-axis.

### 5. How do you plot a graph with the x and y-axis?

At first, we draw and label the x and y-axis. Then we plot the coordinates of the function at various values of the x and y-coordinates. Then we connect the coordinates and plot the graph of a function.

### 6. What is the name of the y-axis?

The vertical axis is known as the abscissa-axis.

### 7. What is the name of the x-axis?

The x-axis is known as the ordinate-axis.
