How to Add a Line Equation in Google Sheets
Google Sheets is a powerful tool for data analysis and visualization. One of the essential features of Google Sheets is the ability to add a line equation to a chart. A line equation is a mathematical expression that describes the relationship between two variables. In this article, we will guide you on how to add a line equation in Google Sheets.

Prerequisites
Before we dive into the process of adding a line equation, make sure you have the following:
- A Google Sheets account
- A chart created in Google Sheets with two variables (x and y)
- Basic understanding of linear regression and line equations
Step 1: Create a Chart
If you haven’t already, create a chart in Google Sheets with two variables (x and y). To do this:
- Select the data range for your chart
- Go to the “Insert” menu and select “Chart”
- Choose the chart type (e.g., scatter chart)
- Customize your chart as needed
Step 2: Calculate the Line Equation
To calculate the line equation, you need to perform a linear regression analysis. Google Sheets has a built-in function for this:
- In a new cell, enter the formula: =LINEST(y_range, x_range)
- Replace “y_range” and “x_range” with the ranges of your y and x variables, respectively
- Press Enter to calculate the line equation
The LINEST function returns an array of values, including the slope (m) and y-intercept (b) of the line equation. The format of the line equation is y = mx + b.
Step 3: Add the Line Equation to the Chart
To add the line equation to the chart:
- Click on the chart to select it
- Go to the “Customize” tab in the Chart editor
- Click on the “Series” dropdown menu and select “Add series”
- In the “Series” section, enter the formula: =m*x+b
- Replace “m” and “b” with the values calculated in Step 2
- Click “Insert” to add the series
The line equation will now be displayed on the chart. (See Also: How To Center In Google Sheets)
Tips and Variations
Here are some additional tips and variations to consider:
- Format the line equation: You can format the line equation to display in a specific format, such as y = 2x + 3.
- Use different line styles: You can change the line style, color, and thickness to distinguish it from other lines on the chart.
- Add confidence intervals: You can add confidence intervals to the line equation to show the range of possible values.
Recap
In this article, we showed you how to add a line equation in Google Sheets. We covered the prerequisites, creating a chart, calculating the line equation using the LINEST function, and adding the line equation to the chart. We also provided some additional tips and variations to consider.
By following these steps, you can easily add a line equation to your charts in Google Sheets and enhance your data analysis and visualization.
