If you had 0 teaspoons of powdered fertilizer, you can't make any liquid fertilizer. So the first point should be (0, 0).
Let's find out how much powdered fertilizer you need to make 1 gallon of liquid fertilizer.
11 / 2 = 5.5
So you need 5.5 teaspoons of powdered fertilizer to make 1 gallon of liquid fertilizer. This is our unit rate.
The 3rd value in the table is 22 teaspoons, it's asking how many gallons of liquid fertilizer you can make with these 22 teaspoons. We can find this out by dividing by our unit rate.
22 / 5.5 = 4
So we have the point (22, 4). We can do the same for the third value.
33 / 5.5 = 6
So we have the point (33, 6).
