To find the slope between two points:
slope = change_in_y/change_in_x
Thus for the points (4, 5) and (6, 8), the slope between them is given by:
slope = (8-5)/(6-4) = 3/2 = 1½ = 1.5

The slope is [2 - (-4)]/[-6 -2] = 6/-8 = -3/4
The slope is dy/dx = 8/4 = 2
The slope is (y2 - y1)/(x2 - x1) That is in this case (-6 + 6)/(4 +4) = 0/8 = 0
The slope for these two points is undefined, or straight up.
Average = (8 + 9 + 5 + 6)/4 = 7Average = (8 + 9 + 5 + 6)/4 = 7Average = (8 + 9 + 5 + 6)/4 = 7Average = (8 + 9 + 5 + 6)/4 = 7
