.Find the slope of the tangent line to the graph of f(x) = x^4 �3x at the point where the abscissa is -1.
f'(x) = 4x^3-3
f'(-1) = 4(-1)^3-3 = -7
------------------------------------
2. Find the slope of the line passing through the following pairs of points
a) (-5, 7) and (1, -5):: m = (-5-7)/(1--5) = -12/6 = -2
-----------------------------------------
b) (4, 3) and (-8, -3):: m = (-3-3)/(-8-4) = -6/-12 = 1/2
--------------------------------
c) (-1, -2) and (6, -2):: m = (-2--2)/(6--1) = 0/7 = 0
--------------------------------
