The information below is the number of miles (in hundreds of miles) the manager’s sales representatives travel per month and the amount of sales (in thousands of dollars) per month.

? = 9

∑ ? = 49

∑ ? 2 = 363

∑ ? = 713

∑ ? 2 = 57803

∑ ?? = 6324

Calculate coefficient R, and find the equation of the regression line.
