Math Problem Statement
Interpret the slope and the y-intercept, if appropriate. Choose the correct answer and fill in any answer boxes in your choice. (Round to three decimal places as needed.) A. The average final exam score of students who miss no classes is enter your response here. It is not appropriate to interpret the slope. B. For every additional absence, a student's final exam score drops enter your response here points, on average. It is not appropriate to interpret the y-intercept. C. For every additional absence, a student's final exam score drops enter your response here points, on average. The average final exam score of students who miss no classes is enter your response here. D. It is not appropriate to interpret the slope or the y-intercept The accompanying data represent the number of days absent, x, and the final exam score, y, for a sample of college students in a general education course at a large state university.
