Based on the correlation coefficient of r=-92, there is a strong negative relationship between the number of absences and the course grades.
The graph represents a linear relationship between x (number of absences) and y (course grades).
Since the relationship is negative, the slope of the graph is negative.
A school compared students' absences to their grades. The school determined the correlation coefficient of each student's absences to course grades was r=-92
