)after the first exam in a large course, the professor surveyed 14 randomly selected students to determine the relation between the amount of time they spent studying for the exam and exam score.  she found that a linear relation exists between the two variables.  the least-squares regression line that describes this relation is  .                  (a)  predict the exam score of a student who studied 2 hours.                  (b)  write an interpretation for the slope. (refer to  lesson 12.2  for this.)                  (c)  write an interpretation for the y-intercept, if appropriate. if not appropriate, explain why not. (again, refer to  lesson 12.2  for this.)  2) in what scenarios would it not make sense to interpret the y-intercept?
