NettetA linear regression line equation is written in the form of: Y = a + bX where X is the independent variable and plotted along the x-axis Y is the dependent variable and plotted along the y-axis The slope of the line is b, and a is the intercept (the value of y when x = 0). Linear Regression Formula NettetTo explain the relationship between these variables, we need to make a scatter plot. To plot the above data in a scatter plot in Excel: Select the data. Go to the Insert Tab > Charts Group. Click on the scatterplot part icon. Choose a scatter plot type from the drop-down menu. Excel plots the data in a scatter plot.
