The table shows the number of absences in a school year and the final exam scores for several students. An equation of the line of fit through (3, 85) and (4, 81) is $y=-4x+97$ . Interpret the slope and the y-intercept.

Absences, x 2 4 1 6 6
Final Exam Score, y 88 81 94 73 74
Absences, x 3 2 1 5 0
Final Exam Score, y 85 89 93 77 97
The slope is
and the y-intercept is
. So, a student with 0 absences is expected to earn a
on the final exam, and the score decreases by about
points per absence.
