- Linear relationship equation: The equation represents a linear relationship between the number of extra credit questions Manon answers correctly () and her overall grade (). The coefficient represents the amount of points each extra credit question adds to her overall grade.
- Y-intercept value: The number is the y-intercept of the equation, which is the value of when is . This means that before adding any points from extra credit questions, Manon's overall grade is .
- Interpretation of : Given that the is the starting value of when no extra credit questions have been answered, it cannot represent the number of opportunities for extra credit (), nor can it represent a threshold that Manon must exceed to pass (), as it is a given starting point, not a condition or a goal.
- Average before extra credit: The also cannot represent Manon's average after adding in her extra credit (), because it is the value before any extra credit is added. The correct interpretation of the in the equation is that it represents Manon's average before adding the extra credit ().
