Identify the problem, positive, negative, zero, or undefined.

Answer 1

------ = ------------ = $3614 per year.  This slope is POSITIVE, and the 
Run        2 yr         function for "tuition as a function of the # of years"
                              is linear and the relationship is proportional.
