Question

A newspaper headline writer found that the more adjectives she put in the titles of her articles, the greater the number of newspapers that were sold that day. This relationship between numbers of adjectives and newspaper sales must be:

Answer 1

Positive.

Step-by-step explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.

On the other hand, nonlinear function has a negative relationship and as such an increase in one variable (input variable) causes a decrease in the other variable (output variable) i.e the variables are inversely proportional.

This ultimately implies that, the graph of a nonlinear function is a curved line and whose direction is constantly changing

In this scenario, the relationship between numbers of adjectives and newspaper sales must be positive because the higher the amount of adjectives put in the titles of her articles, the greater the number of newspapers that would be sold on a particular day.
