1. The table shows the relationship between the number of hours studied and the score on a math test.
2. The independent variable is the number of hours studied.
3. The dependent variable is the score on the math test.
4. The data points are: (0, 60), (1, 65), (2, 70), (3, 75), (4, 80), (5, 85).
5. Plot these points on the coordinate plane.
6. Draw a line of best fit through the points.
7. The equation of the line is y = 5x + 60.
8. The slope is 5, which means for every additional hour studied, the score increases by 5 points.
9. The y-intercept is 60, which means if no hours are studied, the expected score is 60.
10. To predict the score for 6 hours of study, substitute x = 6 into the equation: y = 5(6) + 60 = 90.
11. The predicted score for 6 hours of study is 90.
