Continued from the exercise "NBA, Athlete Performance and Linear Equations".

You are doing a survey with some of the best teams in NBA (score!). Specifically, you want to see whether a long plane ride for the Away Team has an effect on team scoring.

You find that on average, team who have flown for 2 hours before the game score 95 points, and with 4 hours of travel, the average score goes down to 87 points. Long travel could be hurting performance.

1) Complete the following linear equation to model the relationship between x, hours of travel and y, the team score.
y = x +  

2) Explain what the slope means in the equation above.
