Answer:
Here's a graph that represents the relationship between the number of carrots and the number of potatoes in the sack:
Carrots (x) Potatoes (y)
0 0
3 4
6 8
9 12
12 16
As you can see from the graph, if there are 12 carrots in the sack, then there are 16 potatoes in the sack.
You can also use this graph to find the number of potatoes if you know the number of carrots, or to find the number of carrots if you know the number of potatoes. Simply find the number of carrots or potatoes on the x-axis or y-axis, and then follow the line upward or downward until you reach the line that represents the relationship between carrots and potatoes. The number you reach on the other axis is the number of carrots or potatoes.
