Answer:
I believe the answer is B.
Explanation:
By using the process of elimination, we can exclude A because (0,0) is the origin and doesn't exactly represent anything. C can be excluded too because if you look on the x-axis for the number 15, you won't find anything, the graph isn't big enough for that so it's not the answer. Although D could be it, it doesn't represent it well. So therefore, the answer is B because for every person fifteen dollars are paid. I hoped this helped! <3
