*The slope of a regression line (b) represents the rate of change in <math> y </math> as ,math> x </math> changes.  
 
*To find a slope we can use the least squares method.  
 
*To find a slope we can use the least squares method.  
 
*Slope is  found by calculating b as the covariance of x and y, divided by the sum of squares (variance) of x.
