# Linear Function Calculator

A linear equation is defined as an equation that is written in one variable or two variables or so on. This equation will be a linear combination of the variable and a constant.

## What is Linear Function Calculator?

'Linear Function Calculator' is an online tool that helps to find the graph for a given linear function. Online Linear Function Calculator helps you to find the graph for a given linear function in a few seconds.

## How to Use Linear Function Calculator?

Please follow the steps below on how to use the calculator:

**Step 1:**Enter the linear function in the given input box.**Step 2:**Click on the**"Compute"**button to find the graph for a given linear function.**Step 3:**Click on the**"Reset"**button to clear the field and enter a new function.

## How to Plot the Linear Function Graph?

A **linear function** is a function of the form f(x) = ax + b, a ≠ 0. Here, x is variable, a and b are constants.

Please follow the below steps to find the graph for a given linear function:

**Step1:**Write the equation y = f(x) .**Step2:**Substitute any value for x in the given linear function and plot the graph.

Let's see an example to understand briefly.

**Solved Example:**

Compute the graph for y = f(x) = 3x + 5

**Solution:**

Given:** **y = f(x) = 3x + 5

For x = -2, y = -1

For x = -1, y = 2

For x = 0, y = 5

For x = 1, y = 8

For x = 2, y = 11

Plot these points on the graph.

Similarly, you can try the calculator to compute the graph for the following linear functions:

- y = 2x + 5
- y = 5x - 4
