The scatter plot with the line-of-best-fit shown includes an outlier. How will the line-of-best-fit be affected if theoutlier is removed?Ya)The line of best fit is rotated counter-clockwise.b) The line of best fit is rotated clockwise.c)The line of best fit is shifted downward.d)The outlier has no effect on the line of best fit.AВNONE

The outlier is causing the slope of the line of best fit to be less steep than you might expect
