A teacher collects data on the number of hours, s, his students spend studying and the number of hours, t, they spend watching TV each day. He finds that there is a negative linear association between s and t that is best modeled by the equation s=−0.5t+3.6 . What is the meaning of 3.6 in this equation?
A. According to the model, for each additional hour spent watching TV, a student will spend about 3.6 fewer hours studying.

B. The model suggests that students study about 3.6 hours each day.

C. According to the model, a student who does not watch TV studies about 3.6 hours each day.
