To make the prediction, we substitute x = 10 into the given equation:
y = 7.2x + 98.9
y = 7.2(10) + 98.9
y = 72 + 98.9
y = 170.9
Therefore, if a student spent 10 hours on social media, the predicted average final grade percentage would be approximately 171.
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 x and the average final grade percentage y based on the hours. Using the equation of the trend line of tje data y = 7.2x + 98.9 predict the average final grade percentage to tje nearest whole number if a student spent 10 hours on social media
