Question

A teacher uses the function G(x) = -3x + 100 to calculate a student’s grade, G(x), on a test if the student misses x questions on the test. Which statement best describes the slope of the function? 

Answer 1

From the function ; G(x) = -3x +100

The statement desribes that the student will lose 3 points for each question missed.(D)

For example, G(1) = -3 (1) + 100 = -3 +100 =97

G(2) = -3 (2) + 100 = -6 + 100 =94
