The ordered pair in the graph is (8,2). Since x represents the number of teaspoons of lemon juice and y represents the number of cups of lemonade, then the ordered pair (8,2) means the ratio of teaspoons of lemon juice to cups of lemonade is 8 teaspoons of lemon juice : 2 cups of lemonade.
Dividing both numbers in the ratio of 8 teaspoons of lemon juice to 2 cups of lemonade by 2 then gives the ratio 4 teaspoons of lemon juice to 1 cup of lemonade.
An ordered pair will then represent an equivalent ratio if the number of teaspoons (the x-coordinate) is 4 times the number of cups of lemonade (the y-coordinate).
The correct ordered pair is then D. (16,4) . since the x-coordinate of 16 is four times the y-coordinate of 4.
If Oscar chose A as the correct answer, then he switched the ratio. He used a ratio of 1 teaspoon of lemon juice : 4 cups of lemonade since he chose an ordered pair that had a number of cups of lemonade that was 4 times the number of teaspoons of lemon juice.
