    A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (5, 4) 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 (10, 8) on the graph represent? Explain in words. (2 points)

    I assume the relationship is linear in the form y = mx +c If (5,4) is on the line we can calculate the equation gradient m = change in y over change in x, = 4/5 y = 4/5 * x +c 4 = 4/5 * 5 +c c = 0 y = 4/5 x Part a if x = 1 then y = 4/5 part b is 2 times (5,4) so 10 pounds of potatoes cost 8 dollers

    from your data we have that 5 potatoes cost 4 dollar, so the cost of a single potato is: 4/5=...?

    finally, the ordered pair (10,8) represent the point which I get if I consider 10 pounds of potatoes, and which cost is 8 dollars. Infact the costs of 1 pound of potatoes is 0.8 dollars, so the cost of 10 pounds of potatorùes is 0.8*10=8 dollars

    we can say this: "the ordered pair (10,8) represents another point of our graph, more precisely it indicates taht the cost of 10 pounds of potatoes is 8 dollars"
