The grade a student makes on a test varies directly with the amount of time the student spends studying. Suppose a student spends 4 hours studying and makes a grade of 65% on the test. What is an equation that relates the grade earned on a test, g, with the amount of time spent
studying, t, in hours? What is the graph of your equation?
