How to Find Slope on Excel Graph: A Step-by-Step Guide for Beginners

Finding the slope on an Excel graph is easier than you might think. You can quickly determine the slope by creating a scatter plot and adding a trendline. This trendline will give you the equation of the line, and the slope will be part of this equation. Let’s dive into the details to make sure you get it right.

Step-by-Step Tutorial: How to Find Slope on Excel Graph

Creating a scatter plot and adding a trendline in Excel will help you find the slope of your data points. Follow these steps to achieve this.

Step 1: Open Excel

Open Microsoft Excel on your computer to get started.

First things first, open Excel. It’s where all the magic happens. If you don’t have it open, you can’t do anything else!

Step 2: Enter your data

Enter your data into two columns, one for the X values and one for the Y values.

Your data should be organized neatly in columns. Usually, the X values are in the first column and the Y values are in the second. Each row should correspond to a pair of X and Y values.

Step 3: Select your data

Highlight the data you’ve just entered.

Click and drag to highlight all your data. This tells Excel which data to use when it creates the graph and trendline.

Step 4: Create a scatter plot

Go to the ‘Insert’ tab and click on ‘Scatter’ to choose the scatter plot type.

The ‘Insert’ tab is your friend. Look for the scatter plot icon and choose it. This will create a graph that plots your X and Y values against each other.

Step 5: Add a trendline

Right-click one of the data points on the scatter plot and select ‘Add Trendline.’

Right-clicking on a data point will bring up a menu. Select ‘Add Trendline’ from this menu. This will open a new set of options for you to customize your trendline.

Step 6: Display the equation on the chart

Check the box that says ‘Display Equation on chart.’

Within the trendline options, look for a checkbox that says ‘Display Equation on chart.’ Check this box. This will put the equation of the trendline directly on your graph.

After completing these steps, you will see the equation of the trendline on your graph. The slope is the coefficient of the X variable in this equation.

Tips: How to Find Slope on Excel Graph

  • Make sure your data is accurate and correctly entered. Incorrect data can lead to a misleading slope.
  • Use the ‘Format Trendline’ options to choose the trendline type that best fits your data (linear, exponential, etc.).
  • Double-check that the ‘Display Equation on chart’ box is checked. Otherwise, you won’t see the slope.
  • If your data points are too cluttered, you can adjust the axis ranges for better clarity.
  • Practice with example data to get comfortable before applying it to important datasets.

Frequently Asked Questions: How to Find Slope on Excel Graph

What if my data isn’t linear?

If your data isn’t linear, consider using a different type of trendline such as exponential or polynomial. These options are available in the ‘Format Trendline’ menu.

Can I change the appearance of the trendline?

Yes, you can customize the trendline’s color, style, and thickness in the ‘Format Trendline’ options.

What does the slope represent?

The slope represents the rate of change between the X and Y variables. It’s the amount Y changes for a one-unit change in X.

Is it possible to find the slope without a trendline?

Technically, yes. You could calculate it manually using the formula (change in Y) / (change in X), but using a trendline is easier and less error-prone.

Can I use Excel on my phone or tablet to find the slope?

While it’s possible, the desktop version of Excel is more user-friendly for creating and customizing graphs.


  1. Open Excel.
  2. Enter your data.
  3. Select your data.
  4. Create a scatter plot.
  5. Add a trendline.
  6. Display the equation on the chart.


And there you have it! Finding the slope on an Excel graph involves just a few straightforward steps. Once you’ve got your data entered, creating a scatter plot and adding a trendline to display the equation is a breeze. It’s a handy skill to have, whether you’re working on a school project, analyzing business metrics, or just exploring data for fun.

For further reading, consider looking into Excel’s other charting and data analysis features. And don’t forget, practice makes perfect. The more you work with Excel, the more comfortable you’ll become. Now go ahead and give it a try—you’ll be finding slopes like a pro in no time!
