Well I had already answered this question but my answer was deleted for not having a good enough explaination.
The answer would be answer choice D. Jordan needs 1 1/2 cups of diced chicken for three salads. This is basically a common sense question because if you just look at the graph it tells you on the vertical line how many cups of the diced chicken you will need and the horizontal line tells you how much salad it will make.
If you are trying to answer what point A represents, then you would say it represents that you'll need 1 1/2 cups of diced chicken to make 3 salads. I hope this answer explained it clearly enough for you because I can think of literally no other way to make it any easier to show the answer.
