WebFor Excel, let r be Pearson's r, s x the standard deviation and X ¯ x the mean of all the numbers on the x-axis, s y the standard deviation and X ¯ y the mean of all the numbers on the y-axis. Then the slope will be a = r s y s x and y-intercept b = X ¯ y − a X ¯ x, for linear trendline y = a x + b.
