1) Write an equation for the line of best fit 2) Make a prediction for a student who studies 6 hours on what their math grade will be 3) Make a prediction of how many hours a student would need to study for a grade of 40%

1) To write an equation for the line of best fit, we need more information about the dataset or a specific set of data points. The equation will be in the form of y = mx + b, where y represents the predicted math grade, x represents the number of hours studied, m represents the slope of the line, and b represents the y-intercept.

2) Without the equation or more data points, we cannot accurately predict a specific math grade for a student who studies 6 hours. It would depend on factors such as the relationship between hours studied and grades in the given dataset or the specific pattern observed.

3) Similarly, without the dataset or equation, we cannot accurately predict the number of hours a student would need to study for a grade of 40%. It would depend on the pattern observed in the relationship between hours studied and grades in the given dataset.
