The point (1, -3) is in the solution set of 2x - y > 5. Based on this information, which statement about the inequality is true?

• The statement is true because the point (1, -3) lies on the line 2x - y = 5.

• The statement is true because the point (1, -3) is in the region y > 2x - 5.

• The statement is false because the point (1, -3) lies on the line 2x - y = 5.

• The statement is false because the point (1, -3) is in the region y > 2x - 5.

The dance team needs a combined total of 148 cups and plates for its end of year party. The number of plates needed is 1/3 the number of needed cups. Based on this information, is it reasonable for the dance team to order 108 cups and 40 plates?

• Yes because the total number of cups and plates is 148.

• Yes, because the number of plates is 1/3 the number of cups.

• No, because the number of cups is not 1/3 the number of plates.

• No, because the number of plates is not 1/3 the number of cups.
