Exercise 3

Look back at Figure 2, which shows the inverse relationship between ticket prices and game attendance at Gigantic State University, (a) Interpret the meaning of both the slope and the intercept, (b) If the slope of the line were steeper, what would that say about the amount by which ticket sales respond to increases in ticket prices? (c) If the slope of the line stayed the same but the intercept increased, what can you say about the amount by which ticket sales respond to increases in ticket prices?
