Step 3: Add a Trendline

Next, let’s add a trendline to the scatterplot.

To do so, click anywhere on the scatterplot. Then click the green plus (+) sign in the top right corner of the chart and click the box next to Trendline:

Step 4: Display the Slope of the Trendline

To find the slope of the trendline, click the right arrow next to Trendline and click More Options:

In the window that appears on the right side of the screen, check the box next to Display Equation on chart:
