If two quantities are directly related, as one increases, the other increases. Which option best describes their relationship?

Explanation:
Directly related means the two quantities move in the same direction. If one goes up, the other goes up; if one goes down, the other goes down. Since increasing one quantity causes the other to increase, the description that both increase best fits. The other patterns describe opposite movement, a constant value, or one increasing while the other decreases, which don’t match the stated direct relationship. For example, hours worked and earnings rise together.
