- 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 the data, y=–7.2x+98.9, predict the average final grade percentage, to the nearest whole number, if a student spent 10 hours on social media.(1 point) Responses The average final grade is 27% if a student spent 10 hours on social media. The average final grade is 27% if a student spent 10 hours on social media. The average final grade is 99% if a student spent 10 hours on social media. The average final grade is 99% if a student spent 10 hours on social media. The average final grade is 7.2 if a student spent 10 hours on social media. The average final grade is 7.2 if a student spent 10 hours on social media. The average final grade is 92% if a student spent 10 hours…What is a trend line that shows the most accurate relationship between x and y and is very close to most of the data pointsHow does one do a trend analysis?
