C. (-4, 7) and (-9, 5)
D. (3, -7) and (8, 4)

The slope of a line can be calculated by using the formula: \[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} \] Given the choices, let's calculate the slope for each pair of points: A. (3, 6) and (-1, -4): \[ \text{slope} = \frac{-4 - 6}{-1 - 3} = \frac{-10}{-4} = 2.5 \] B. (-4, 2) and (7, -1): \[ \text{slope} = \frac{-1 - 2}{7 - (-4)} = \frac{-3}{11} \neq 5 \] C. (-4, 7) and (-9, 5): \[ \text{slope} = \frac{5 - 7}{-9 - (-4)} = \frac{-2}{-5} = 0.4 \] D. (3, -7) and (8, 4): \[ \text{slope} = \frac{4 - (-7)}{8 - 3} = \frac{11}{5} \neq 5 \] Therefore, the points that form a line with a slope of 5 are not among the given choices.
