the question relating to the graph picture

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 Relationship Line As the number of hours spent studying rises, the average grade received rises. As the number of hours spent watching TV rises, the average grade received falls. As the number of hours spent studying falls, the likelihood of getting an A falls. True or False: Line A has a slope of zero. O True O False
