A linear relationship exists between the weight of candy purchased (w) and the cost of the candy (C).
·  2 pounds of candy costs 5 dollars.
·  6 pounds of candy costs 7 dollars.    
Which of the following best shows the relationship between the weight and the cost of the candy?

• C = 0.5w + 4

• C = 0.5w - 0.5

• C = 2w - 8

• C = 2w + 1

An experiment is conducted where weights are added to a spring which is then measured.
·  When 4 grams are added to the spring, the spring stretches 12 centimeters. 
·  When 6 grams are added to the spring, the spring stretches 18 centimeters. 
·  Let w represent the amount of weight added to the spring.
·  Let s represent the distance the spring is stretched.
Which of the following is true about the relationship between w and s?

• There is a direct variation between w and s because s = 3w.

• There is a direct variation between w and s because ws = 48.

• There is an inverse variation between w and s because s = 3w.

• There is an inverse variation between w and s because ws = 48.
