From the markings that you had written and erased on your graph, it seems that you already have an idea of what you're supposed to do. Is it that you're having trouble scaling your graph on the provided sheet given the particular data? Or do you have a conceptual question with respect to the instructions?
I've provided the image of the graph according to my understanding of the instructions as stated in 1 and 2, and I've also attached the corresponding Excel spreadsheet that I used to create the graph.

That said, please feel free to let me know if you have any clarifications, comments, or questions.
