    A proportional relationship between the number of pounds of cabbage (x) and the price in dollars (y) is graphed, and the ordered pair (5, 3) is on the graphed line. Part A: What is the price of 1 pound of cabbage? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (10, 6) on the graph represent? Explain in words. (2 points)

    Since x is the # of cabbages and y is the cost, the ordered pair (5,3) means that 5 pounds of cabbage cost 3 dollars. Therefore, each pound of cabbage is 3/5 dollars, or 60 cents. The ordered pair (10,6) represents the cost of 10 pounds of cabbage being 6 dollars.
