## What is used to illustrate an independent relationship between two variables? a. An upward-sloping curve b. A downward-sloping curve c. A hill-shaped curve d. A horizontal or vertical line

To determine

The shape of line used to illustrate the independent relationship between two variables.

### Explanation of Solution

When the two variables are concerned, there might be relation between the two or there might not be any relation between the two. There are different shapes of curves used to illustrate the relation between the two variables. When there is a relation between the two, there will be a curved line and when there is no relation, there will be a vertical or horizontal straight line.

Option (d):

When there is no relation between the two variables, any change in one variable will not affect the other. This means that whatever be the change in variable one, the variable two will remain constant. The lines used to illustrate this relation is vertical or horizontal straight line that indicates the independency of the variables. Thus, option 'd' is correct.

Option (a):

A upward sloping curve indicates a positive relationship between the two variables. When the variable one increases, it will lead to the increase in the variable two and vice versa...
