Graph each proportional relationship. Part A Jenny is making broccoli cheddar soup and her recipe calls for 2 1/4 cups of broccoli, x, for every 3/4 cup of cheddar cheese, y. Assume the situation is proportional. (Graph the relationship on the provided graph.)

• Plot the point (2.25, 0.75) and draw a straight line through the origin and this point.

• Plot the point (0.75, 2.25) and draw a straight line through the origin and this point.

• Plot the point (3, 1) and draw a straight line through the origin and this point.

• Plot the point (1, 3) and draw a straight line through the origin and this point.

A carnival game uses a fair spinner with 16 sections. There are 2 white sections, 4 red sections, and 10 blue sections on the spinner. Part A Find the probability of each event. Express your answer as a fraction in simplest form.

• P(blue) = 10/16 = 5/8 P(green) = 0/16 = 0 P(red) = 4/16 = 1/4

• P(blue) = 8/16 = 1/2 P(green) = 2/16 = 1/8 P(red) = 6/16 = 3/8

• P(blue) = 4/16 = 1/4 P(green) = 2/16 = 1/8 P(red) = 10/16 = 5/8

• P(blue) = 2/16 = 1/8 P(green) = 4/16 = 1/4 P(red) = 10/16 = 5/8
