Question
The scatter plot below shows the number of hours a group of students reported studying for an exam as well as the grade each student earned on the exam.
The equation of this trend line is y = 5.03x + 56. Based on this information, what can we predict a student’s grade would be if they spend no time studying for the exam?

To predict a student's grade if they spend no time studying for the exam, we can substitute \( x = 0 \) into the trend line equation \( y = 5.03x + 56 \).
Substituting \( x = 0 \):
\[
y = 5.03(0) + 56 = 56
\]
So, if a student spends no time studying, we can predict their grade would be **56**. Therefore, the correct response is:
56
Substituting \( x = 0 \):
\[
y = 5.03(0) + 56 = 56
\]
So, if a student spends no time studying, we can predict their grade would be **56**. Therefore, the correct response is:
56
