Add a regression line without the error bars to the scatterplot. # Load packages library(ggplot2) library(dplyr) library(moderndive) # Plot ggplot(evals, aes(x = bty_avg, y = score)) + geom_point() + labs(x = "beauty score", y = "score") + ___(___ = ___, ___ = ___). Previously you visualized the relationship of teaching score and "beauty score" via a scatterplot. Now let's add the "best-fitting" regression line to provide a sense of any overall trends. Even though you know this plot suffers from overplotting, you'll stick to the non-jitter version
