a. To compute the regression equation, we first need to calculate the slope and intercept of the regression line. We can use the following formulas:

slope (b) =   
intercept (a) = (?Y - b?X) / N

where N is the number of data points, ?X is the sum of X values, ?Y is the sum of Y values, ?XY is the sum of X times Y, and ?X^2 is the sum of X squared.
