Question

Which of the following slopes show that the set of points C(1, 1), D(3, -4), E(5, 8) are not collinear? 1/3, -5/3, -2/5 1/2, 3, 5 -1, 1/2, -3/5 6, -5/2, 7/4

Answer 1

Answer:

6, -5/2, 7/4

Step-by-step explanation:

Slope CD: (-4-1)/(3-1) = -5/2

slope DE: (8--4)/(5-3) = 12/2 = 6

slope CE: (8-1)/(5-1) = 7/4

Answer 2
