How To Find The Equation Of A Line On Google Sheets
In this article, we will explore the steps to find the equation of a line on Google Sheets. This is a useful skill for anyone who needs to analyze and visualize data in a spreadsheet.
What is the Equation of a Line?
The equation of a line is a mathematical formula that describes the relationship between the x and y coordinates of a point on the line. It is typically written in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

Step-by-Step Guide to Finding the Equation of a Line in Google Sheets
To find the equation of a line in Google Sheets, follow these steps:
Step 1: Select the Data Range
Select the range of cells that contains the x and y coordinates of the points on the line. Make sure to select the entire range, including the headers.
Step 2: Calculate the Slope (m)
To calculate the slope of the line, use the following formula:
m = (y2 - y1) / (x2 - x1)
Replace x1, y1, x2, and y2 with the coordinates of two points on the line. You can use the AVERAGE function to calculate the average of the x and y values if you have multiple points.
Step 3: Calculate the Y-Intercept (b)
To calculate the y-intercept of the line, use the following formula:
b = y - mx
Replace y with the y-coordinate of a point on the line and m with the slope calculated in Step 2.
Step 4: Write the Equation of the Line
Once you have calculated the slope and y-intercept, you can write the equation of the line in the form y = mx + b. (See Also: How To Add A Column Chart In Google Sheets)
Step 5: Verify the Equation
To verify that the equation is correct, plug in the coordinates of a point on the line and make sure that the calculated y-value matches the actual y-value.
Example: Finding the Equation of a Line in Google Sheets
In this example, we will find the equation of a line that passes through the points (1, 2) and (2, 4) in Google Sheets.
| x | y |
|---|---|
| 1 | 2 |
| 2 | 4 |
Using the formulas above, we can calculate the slope and y-intercept:
m = (4 - 2) / (2 - 1) = 2 b = 2 - 2(1) = 0
The equation of the line is y = 2x + 0, or simply y = 2x.

Frequently Asked Questions
What is the equation of a line?
The equation of a line is a mathematical formula that describes the relationship between the x and y coordinates of points on the line. In the context of Google Sheets, the equation of a line is used to create a linear trendline that can be used to forecast future data or identify patterns in existing data.
How do I find the equation of a line in Google Sheets?
To find the equation of a line in Google Sheets, you can use the LINEST function, which is a built-in formula that calculates the equation of a line based on a set of data points. The LINEST function takes several arguments, including the range of cells that contain the x and y coordinates of the data points, as well as the slope and y-intercept of the line.
What is the slope of a line?
The slope of a line is a measure of how steep the line is. It is calculated by dividing the change in the y-coordinate (Δy) by the change in the x-coordinate (Δx). In Google Sheets, the slope of a line is used to determine the direction and steepness of the line.
How do I use the LINEST function in Google Sheets?
To use the LINEST function in Google Sheets, you can enter the formula =LINEST(y_range, x_range, const) in a cell, where y_range is the range of cells that contain the y-coordinates of the data points, x_range is the range of cells that contain the x-coordinates of the data points, and const is an optional argument that specifies whether the line should pass through the origin (0,0).
Can I use the LINEST function to find the equation of a line for a set of data points that are not linear?
No, the LINEST function is only suitable for finding the equation of a line for a set of data points that are linear. If your data points are not linear, you may need to use a different statistical method or formula to find the equation of the line.
