# Linear Graph Calculator

A linear graph is the graphical representation of a straight line which is represented by the equation of the form **'y = mx + c'**.

## What is a Linear Graph Calculator?

'**Online Linear Graph alculator**' is a free online tool that sketches the linear graph passing through two points within a few seconds.

## How to Use the Linear Graph Calculator?

Follow the steps mentioned below to sketch the linear graph of the line passing through two points.

**Step 1**- Enter the values of x_{1}, x_{2}, y_{1}, y_{2}.**Step 2**- Click on "**Draw**" to sketch the linear graph passing through those points.**Step 3**- Click on "**Reset**" to clear the fields and enter the new points.

## How to Draw a Linear Graph?

Consider the following steps to plot a linear graph:

- Select the two points (x
_{1},y_{1}), (x_{2}, y_{2}) to draw the linear graph. - Mark the two points on the graph by using their
**x**and**y**coordinates. - Then use a ruler to join the two points with a line passing through those points.

The equation of the line can be found by substituting both the points in the linear equation y = mx + c. The slope 'm' and the vertical intercept 'c' can be found using both the equations you get from the two points.

Let's learn through an example how to sketch a linear graph.

**Solved Examples on Linear Graph Calculator**

**Example 1:**

Sketch a linear graph passing through points A(1,2) and B(2,3) and verify it using linear graph calculator.

**Solution:**

In the first step, we have to mark the two points A and B on the graph paper. To mark point A, travel 1 unit towards the positive x-axis from the origin (0,0) then 2 units upward. To mark point B, travel 2 units towards the positive x-axis from the origin (0,0) then 3 units upward.

After marking the two points A and B use a ruler and sketch the line passing through the two points.

Now, use linear graph calculator and sketch the graph of the following points.

1) (2,3), (3,4)

2) (5,6), (7,2)
