So, your x-axis should be the input, milk, to make thr output, cheese (your y-axis).
With no milk, you have no cheese, so (0,0)
With 65 gallons of milk, there are 52 pounds of cheese, so (65,52).
With 130 gallons of milk, you have 104 pounds of cheese, so (130,104).
You should have a graph starting at the origin and pointed up and to the right going through these points.
