On a final exam with every question counting for the same number of points, answering 10 questions correct is worth 15 points. The line represents the relationship between the number of questions correct and the number of points earned on the test. The point (1, 1.5) is on the line. Write an equation that represents the proportional relationship between test questions and points earned.

Explain the meaning of the point (1, 1.5) in terms of the situation.

⇒ ?= 37*40/100= 14.8

37% of 40 is 14.8~
