Look at Figure, 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?
The Law of Demand states that as the price of a good increases, ceteris penbus, the

The following graph contains four lines (A, B, C and D), each of which has a slope that is either positive, negative, zero, or infinite.
For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the previous graph has a slope that reflects this type of relationship.
Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled “ The average grade received" and Y-axis should be labeled "The number of hours spent studying".
Scenario: As the number of hours spent studying rises, the average grade received rises.
Relationship: Positive or Negative
Line: A, B, C, or D?
Scenario: As the number of hours spent watching TV rises, the average grade received falls.
Relationship: Positive or Negative
Line: A, B, C, or D?
Scenario: As the…
