A new smartphone game deducts points from your account when you purchase tokens within the game. If you purchase a large number of tokens at one time, the game deducts fewer points from your account overall. The scatter plot below displays data for eight users' accounts. The relationship between the number of tokens purchased is displayed on the x-axis and the number of points deducted is displayed on the y-axis. Which of the following statements correctly describe the scatter plot shown? Select ALL that apply.

• There are no outliers.

• The scatter plot shows a linear association.

• The scatter plot shows a positive association.
