Slope between points (-2, -1) and (-1, -3/2):
Slope = (-3/2 - (-1))/(-1 - (-2)) = (-3/2 + 1)/1 = -1/2
Slope between points (-1, -3/2) and (0, 2/3):
Slope = (2/3 - (-3/2))/(0 - (-1)) = (2/3 + 3/2)/1 = 13/6 or approximately 2.167
Slope between points (0, 2/3) and (2, 5/2):
Slope = (5/2 - 2/3)/(2 - 0) = (5/2 - 2/3)/2 ≈ 8.67
Slope between points (2, 5/2) and (4, 7):
Slope = (7 - 5/2)/(4 - 2) = (7 - 5/2)/2 = 9/4 or 2.25
