A proportional relationship between the number of pounds of lettuce (x) and the price in dollars (y) is graphed, and the ordered
pair (5, 3) is on the graphed line. Part A: What is the price of 1 pound of lettuce? Show your work. (8 points) Part B: What does the ordered pair (10, 6) on the graph represent? Explain in words.
The point (5,3) means that you get 5 pounds of lettuce for 3 dollars, which means that one pound of lettuce would cost 3/5 dollars.
B) It tells us that 10 pounds of lettuce costs $6.
The x value of the point on the this graph tells us the number of pounds of lettuce and the y value of the point tells us the cost of those pounds of lettuce.
These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.
