First, let's calculate the correlation coefficient   
Compute the individual products of the    values for each data pair.
Compute the sum of these products.
Compute the sum of    values   , the sum of Y values    the sum of squared    values   , and the sum of squared Y values   Apply the correlation coefficient formula:

  
Next, let's find the regression line.   
1. Compute the slope (b) using the formula:
  Where?    are the standard deviations of    respectively.
2. Compute the y-intercept (a) using the formula:
