2. The Rules of War Place your team’s battleships on the coordinate plane. After a given amount of time, I will call on someone from the team to answer. (Make sure everyone on your team agrees on an answer!) If you answer a question correctly, you get to fire on the opposing team by stating ordered pairs. If you answer incorrectly, you do not get to fire. Try to sink the opposing team’s battleships. May the most knowledgeable team win!

40. No, it fails the vertical line test.

41. Explain the Correlation. The temperature outside and the number of people at the beach.

42. Positive because as the temperature increases, the number of people at the beach increases.

43. Explain the Correlation. A person’s weight and their math grade.

44. No correlation because a person’s weight does not effect their math grade.

45. Explain the Correlation. The amount of time spent exercising and a person’s weight.

46. Negative because as time spent exercising increase, a person’s weight decreases.
