A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)

The point (4,3) means that 4 lbs. of potatoes = \$3. Therefore, we have:

4 lbs / \$3  = 1lb / x       cross-multiply

4x = 3      divide by 4

x = 3/4 dollars = \$.75 per pound

The point (8,6) means that 8 lbs. of potatoes = \$6.
