Question: The following data shows the number of hours studied by a group of students and their corresponding test scores. (Hours studied, test score)= ( 1, 60), (2, 65), (3, 70), (4, 75), (5, 80). Using the data, write an equation that models the relationship between hours studied and test scores. Then, predict the test score for a student who studied for 6 hours.
A) The equation is y=5x+55; the predicted score for 6 hours is 85.
B) The equation is y=5x+60; the predicted score for 6 hours is 90.
C) The equation is y=10x+50; the predicted score for 6 hours is 95.
D) The equation is y=2x+60; the predicted score for 6 hours is 80.
