For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, a 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 se vertical axis. For example, in the first scenario, X-axis should be labeled" The average grade received" and Y-axis should hours spent studying". Scenario Relationship Line As the number of hours spent studying falls, the likelihood of getting an A falls. Negative As the number of hours spent watching TV rises, the average grade received falls. As the number of hours spent studying rises, the average grade received rises. Positive True or False: Line C has a slope of infinity. O True O False The following graphs show the relationship between the price of apples and the quantity of apples supplied in two different and South. Assume that the two lines are parallel.
