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.

previous graph has a slope that reflects this type of relationship.
X-axis
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.
As the number of hours spent studying falis, the likelihood of getting an A falls.
As the number of hours spent watching TV rises, the average grade received falls.
