Question

Question 7 of 10 Kim earns 3 points for every correct answer on a test. The equation y 3r shows her total points, which depends on the number of correct answers. Select the graph with the correctly labeled axes for this situation.

Answer 1

Since Kim earns 3 points for every correct answer, in the horizontal axis we have the number of correct answers Kim got, and in the vertical axis we have the corresponding total of points that each number of correct answers is related.

Also, for each unitary increase in the x-axis, the y-axis increases 3 units, because each correct answer is worth 3 points.

The option that shows these relations is the graph in option D.
