Answer:
I can't seem to scan so I'll just tell you the points. For the line for the 6 minute questions, the points are: (1, 1) (2, 2) (3, 3) (4, 4) (5, 5) (6, 6) and (7, 7). For the line representing the 2 minute questions, the points are: (1, 18) (2, 15) (3, 13) (4, 9) (5, 6) (6, 3) and (0, 7)
Essentially, it's a graph showing the possible numbers of each question.
Hope this helps :)
