Draw a scatter plot that shows a negative, linear association and has one clear outlier. Circle the outlier. Have at least 5 total points. 

The fitted line has a slope of 5. What is the best interpretation of this slope?

• We would predict that the diameter of 0 would have a volume of 5.

• We would predict that the diameter of 5 would have a volume of 0. 

• We would predict that the diameter of 1 would have a volume of 5. 

• We would predict that the diameter of 5 would have a volume of 1.

Using the trend line, when the temperature is 21 degrees, what would the sales amount be?

• $480

• $425

• $500

• $450

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

• y = 3x

• y=4x-2

• y = -x + 5

• y = -5x

• The relationship is not linear
