i. It tells us if the linear relationship between the Number of Hours Spent Studying and the Midterm Grade is a positive or negative relationship,
ii. It tells us the average Midterm Grade when the number of Hours Spent studying is zero.
iii. It tells us that for every additional Hour, Spent Studying the average amount that the Midterm Grade should increase or decrease.
