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.
Part B: What does the ordered pair (10, 4) on the graph represent? Explain in words.

Answer 1

Part A - 2/5 of a dollar

Part B - It shows that 10 pounds of cabbage cost $4

Explanation:

If 5 pounds cost $2 then 1 pound costs 2/5 of a dollar.

(10,4) - 10 is the x-axis which is pounds and 4 is the y-axis which is $. So 10 pounds cost $4.
