A 2-column table with 10 rows. The first column is labeled x with entries 0.5, 1, 1, 1.5, 2, 2, 2.5, 3.5, 3.5, 4. The second column is labeled y with entries 1, 1, 2, 3, 2, 5, 4, 5, 6, 7. A graph shows the horizontal axis numbered 1 to 4 and the vertical axis numbered 1 to 7. A line increases from 0 to 4.
Devin recorded the number of hours he played a video game, x, and the levels he achieved, y. The regression calculator shows the equation for the line of best fit. Use the equation to interpolate the values and estimate the time it would take him to get to level 5. Round to the nearest half hour.
