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 slope. How many points does the average final grade decrease for 1 hour on social media?(1 point)

Answer 1

The slope of the trend line is \(-7.2\). This indicates that for each additional hour a student spends on social media, their average final grade decreases by approximately 7.2 points. Thus, the average final grade decreases by 7.2 points for every 1 hour spent on social media.
