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)

Best ResponseYou've already chosen the best response.0part A. I call with p the price of 1 pound of potatoes, so I can write this proportion: \[\Large 3:4 = p:1\]

Best ResponseYou've already chosen the best response.0since if 4 pounds cost $3 than 1 pound costs p, namely those ratios 4/3 and 1/p have to be equal each other: \[\frac{4}{3} = \frac{1}{p}\]

Best ResponseYou've already chosen the best response.0or, taking the inverse of those ratios, we can write: \[\frac{3}{4} = \frac{p}{1}\]
