This will add the line of the linear regression as well as the standard error of the estimate (in this case +/- 0.01) as a light grey stripe surrounding the line: We can add some style parameters using theme_bw() and making custom labels using labs(). This means that for every 1% increase in biking to work, there is a correlated 0.2% decrease in the incidence of heart disease.
