The formula of a slope:

We have the points (-8, -20) and (5, 2). Substitute:

Answer: The slope is 
Divide 6 by -8 to get the variable alone!
6/-8 < division< equation
Answer:
3
Step-by-step explanation:
The measure of the slope is
at x = a
Differentiate using the power rule
(a
) = na
Given
y = x³ - 1, then
= 3x²
The slope at (1, 0) is
= 3(1)² = 3
