how can you use the graph for exercise 2 to find how many cups are in 9 quarts

We can find the number of cups in 9 quarts by finding the point at which the 9 quarts intersect with cups.
The graph relates quarts to cups by using the ratio of 1 quart = 2 cups.
Once we complete the chart with the equivalence cups to quarts we can use it to identify how many cups are there in x number of quarts or how many quarts are there in x number of cups. Just follow this process:
Based on this, the number of quarts in 9 units should be 28, this is not shown in your graph since we first need to complete it.
