Question

A proportional relationship between the number of pounds of cabbage (x) and the price in dollars (y) is graphed, and the ordered pair (5, 2) 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.
Part B: What does the ordered pair (10, 4) on the graph represent? Explain in words.

Answer 1

I had a question like this but the problem was (5,4) not (5,2)I did this,
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.

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 dollars
