The graph shows Linda's math scores versus the number of hours spent doing math homework. A graph titled Lindas Math Scores shows Hours of Practice in a Week on x axis and Math Scores on y axis. The x axis scale is shown from 0 to 5 at increments of 1, and the y axis scale is shown from 0 to 50 at increments of 5.The ordered pairs 0, 10 and 0.5, 15 and 1, 20 and 1.5, 18 and 2, 25 and 2.5, 26 and 3, 29 and 3.5, 32 and 4, 35 and 4.5, 45 and 5, 50 are shown on the graph. A straight line joins the ordered pairs 0, 10 and 5, 45.7.

What will most likely be Linda's approximate math score if she does math homework for 7 hours a week?

62.5 points
77.5 points
82.5 points
