True or False:

The graph shows a negative association.

• True

• False

A group of hikers is descending, and the elevation of several of the hikers after a certain number of minutes is shown in the scatter plot.

True or False:

The scatter plot is demonstrating a linear relationship.

• True

• False

Match the scatter plot to the equation that could represent the equation of its trend line.
