To be written on the axis of a graph,suggest two quantities that might be described by the statement.
1) When one quantity decreases, the other decreases.
2) When one quantity decreases, the other increases.
3) When one quatity increases, the other decreases.
4) Both quantities change independently of each other.
Plz help.
I can't answer that without seeing the graph. (2) and (3) seem to describe the same relationship. If (4) were true, you'd have a scatter plot, or a 3-D graph, or no graph at all.
To suggest two quantities that might be described by each statement, we can consider the following possibilities:
1) When one quantity decreases, the other decreases: This statement suggests a negative correlation between the two quantities. For example, the number of hours spent studying and the test scores achieved could show this relationship. As studying less leads to lower test scores.
2) When one quantity decreases, the other increases: This statement suggests an inverse relationship between the two quantities. For instance, the amount of money spent on shopping and the amount of money saved could exhibit this relationship. As spending less on shopping leads to more money being saved.
3) When one quantity increases, the other decreases: As mentioned earlier, this statement has the same interpretation as the first statement. It implies a negative correlation between the two quantities. An example could be the production of goods and their price. As the production of goods increases, their price generally decreases.
4) Both quantities change independently of each other: In this case, each quantity does not affect the other, and they change freely based on their own conditions. This situation is often observed in scatter plots, where there is no observable relationship between the variables. For example, the age and shoe size of a group of people may show this independent relationship.
It's important to note that without visualizing the graph or having more context about the specific quantities, it is difficult to provide more precise answers.
