Sleep vs. watch TV time

Using a data set relating about number of episodes I watch of TV in a day (x) versus number of hours of sleep I get that night (y), I construct the linear model
y=−0.6x+11

Which of the following is a general observation that you can make from this model?

a) If I watch more TV, I generally sleep less.
b) If I watch more TV, I generally sleep more.
c) If I watch less TV, I generally sleep less.

Result

q = (Correct answer is: a) Wrong answer

Solution:

f(x)=y=0.6x+11 k=y=0.6 y<0  q=a
