Answer:

  • 4. -3
  • 5. -1/2
  • 6. 1/2
  • 7. 4
  • 8. 0
  • 9. undefined

Step-by-step explanation:

Use of slope formula:

  • m = (y2 - y1)/(x2 - x1)

4.

  • m = (7 - 4)/(1 - 2) = 3/-1 = -3

5.

  • m = (-2 - 0)/(3 - (-1)) = -2/4 = -1/2

6.

  • m = (5 - 3)/(5 - 1) = 2/4 = 1/2

7.

  • m = (3 - 0)/(3.5 - 4.25) = 3/0.75 = 4

8.

  • m = (3/4 - 3/4)/(5 - 2) = 0

9.

  • m = (2 - 3)/(7.5 - 7.5) = -1/0 = undefined
