Exhibit 2A-4 -The curve in Exhibit 2A-4 represents a(n)

Suppose the value of one variable rises while the value of another variable falls; then the slope of the relationship between the two variables is between 0 and 1.

A positive relationship represents a situation where an increase in one variable is associated with an increase in the other variable. Draw three graphs that represent a positive relationship.
