## How do you graph a linear regression in Excel?

We can chart a regression in Excel by highlighting the data and charting it as a scatter plot. To add a regression line, choose “Layout” from the “Chart Tools” menu. In the dialog box, select “Trendline” and then “Linear Trendline”. To add the R2 value, select “More Trendline Options” from the “Trendline menu.

#### What is the formula for linear regression?

Linear regression. Linear Regression Equation A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable, ‘b’ is the slope of the line, and ‘a’ is the intercept. The linear regression formula is derived as follows. Let ( Xi , Yi ) ; i = 1, 2, 3,…….

How do you graph linear equations in Excel?

Excel can graph linear functions. Highlight the data you want to graph by clicking at the top left of the data and dragging the mouse to the bottom right. Click on the “Insert” tab. Select “Line graph” and choose “2-D Line.”. Excel will draw the graph for the linear equation based on the table of values you input.
