7TH Practice Test 2

Graph each proportional relationship. Part A: Layla is making carrot barley soup and her recipe calls for 1 1/2 cups of barley, y, per 3 cups of carrots, x. Assume the situation is proportional.

• A straight line passing through (0,0) and (3,1.5)

• A straight line passing through (0,0) and (1.5,3)

• A straight line passing through (0,0) and (3,3)

• A straight line passing through (0,0) and (1,1.5)

Graph each proportional relationship. Part B: Graph y = 2x.

• A straight line passing through (0,0), (1,2), (2,4), (3,6)

• A straight line passing through (0,0), (1,1), (2,2), (3,3)

• A straight line passing through (0,0), (1,3), (2,6), (3,9)

• A straight line passing through (0,0), (1,4), (2,8), (3,12)

Graph each proportional relationship. Part C: Graph the points for the table: x: 3, 6, 9; y: 4, 8, 12.

• Points (3,4), (6,8), (9,12) plotted on the graph

• Points (3,3), (6,6), (9,9) plotted on the graph

• Points (3,6), (6,12), (9,18) plotted on the graph

• Points (4,3), (8,6), (12,9) plotted on the graph

A card game uses a deck of 24 cards with shapes. There are 16 triangles, 6 squares, and 2 pentagons on the cards. Part A: Find the probability of each event. Express your answer as a fraction in simplest form.

• P(triangle) = 16/24 = 2/3; P(pentagon) = 2/24 = 1/12; P(hexagon) = 0/24 = 0

• P(triangle) = 6/24 = 1/4; P(pentagon) = 2/24 = 1/12; P(hexagon) = 2/24 = 1/12

• P(triangle) = 16/24 = 2/3; P(pentagon) = 6/24 = 1/4; P(hexagon) = 2/24 = 1/12

• P(triangle) = 2/24 = 1/12; P(pentagon) = 16/24 = 2/3; P(hexagon) = 6/24 = 1/4
