In the example below, we could look at the data. The b is the slope that is equal to r*(sy/sx) where r is the correlation coefficient, sy is the standard deviation of y values and sx is the standard deviation of x value. If the scatterplot dots fit the line exactly, they will have a correlation of 100% and therefore.
