Question

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 point)

Answer 1

The y-intercept is 98.9, which means the predicted average final grade for a student who spends 0 hours on social media is about 98.9 (≈99%).
