 Which of the following best describes the trend?

Quizplus · Accepted Answer

As the chickens get older, their egg production decreases. This relationship is inversely proportional. This means that as one variable increases, the other decreases.
The opposite of this is when variables are proportional.  This means that as one variable increases, the other also increases in response.  This means that the only possible answers are "the trend is linear and the egg production decreases with age" and "the trend is not linear and the egg production decreases with age but levels off as chickens get older."
The trend is linear and the egg production decreases with age is not the answer because the relationship is not linear. When a relationship between two variables is linear, the graph resembles a line. When the relationship is not linear it does not resemble a line.
In this case, the relationship is not linear. As the chickens get older, egg production levels off to remain at similar levels.
