Your teacher surveyed the class to determine the number of hours that each student spent on social media. Your teacher created a table and scatterplot graph that displayed the number of hours and the average final grade based on the hours. The trend line (equation) for the data is y=−7.2x+98.9. Interpret the y-intercept. What is the average grade if a student was on social media for 0 hours?(1 poin
The y-intercept of the trend line represents the predicted average final grade for a student who spent 0 hours on social media. In this case, the y-intercept is 98.9. This means that, on average, a student who did not spend any time on social media is predicted to receive a final grade of 98.9.
