Answer:
1) Δy = 9, Δx = -6, slope = Δy/Δx = -3/2
2) Δy = 7, Δx = -3, slope = Δy/Δx = -7-/3
3) Δy = -6, Δx = 6, slope = Δy/Δx = -1
4) Δy = 5, Δx = 8, slope = Δy/Δx = 5/8
5) Δy = 3, Δx = 11, slope = Δy/Δx = 3/11
6) Δy = 7, Δx = 6, slope = Δy/Δx = 7/6
7) Δy = 2, Δx = -5, slope = Δy/Δx = -2/5
8) Δy = 8, Δx = 4, slope = Δy/Δx = 2
