In order for applicants to work for the foreign-service department, they must take a test in the language of the country where they plan to work. The data below shows the relationship between the number of years that applicants have studied a particular language and the grades they received on the proficiency exam.  Find the equation of the regression line for the given data and answer the following questions.

(a) Find the slope of the equation of the regression line for the above data and interpret.

Round the slope to nearest thousandth.  (e.g.  1.3589 would enter as 1.359)

(b) Find the y-intercept of the equation of the regression line for the above data and interpret if appropriate.  If the interpretation is not appropriate, explain why.

Round the y-intercept to nearest thousandth.  (e.g.  1.3589 would enter as 1.359)
