A teacher collected data to see if there was a relationship between how a student performed on a test and how long the student
spent studying. A trend line has been drawn for the data. The equation for the line is: y -0.80x + 59. Which BEST interprets the slope
of the linear model?
A student who studied for 30 minutes is predicted to earn a grade of 80
points.
Eliminate
A student who did not study for the test is predicted to earn a grade of 59
points.
Each additional minute of study time is associated with an additional 0.8
points on the test.
Each additional 0.80 minutes of study time is associated with an additional
