An equation of direct variation is of the form

M = k X

where k us a constant. In your case M might be total money earned and X is the number of students.

Clearly M = 0.65 X

The graph is a straignt line through the origin with slope 0.65. It goes through the points

M = 0, X = 0 (the origin)

and

M = 13, X = 20
