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.   Y-axisX-axisBDCA   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 “ ice-cream" and Y-axis should be labeled "The temperature". Scenario Relationship Line As the temperature rises, the demand for ice-cream rises. Negative         As the temperature rises, the demand for hot cocoa falls. Positive         As the temperature falls, the demand for popsicles falls. Negative           True or False: Line B has a slope of infinity.…
