A grocery store sells sliced cheddar cheese by weight. The relationship between the amount of cheddar cheese in pounds, xx, and the total cost in dollars of the sliced cheddar cheese, yy, is represented by a graph drawn in the xy-plane.

Question

If the point (4, comma, 164,16) lies on the graph, what does the ordered pair (4, comma, 164,16) indicate?

Answer 1

The ordered pair \((4, 164.16)\) on the graph indicates that when you purchase 4 pounds of sliced cheddar cheese, the total cost is $164.16.

In general, the first component of the ordered pair represents the weight of the cheese in pounds (in this case, 4 pounds), and the second component represents the total cost in dollars (in this case, $164.16). Thus, this point reflects a specific transaction or relationship between the amount of cheese purchased and its cost.
