In a scatter plot of exam scores (y) vs. hours studied (x), most points are clustered around x = 3 to x = 5 hours. One point is an outlier: it has x = 20 hours (far from the others) and y = 95 (consistent with what the regression line predicts). If this outlier were removed, what would likely happen to the regression line's slope?
