The difference quotient is a measure of the average rate of change of the function over an interval (in this case, an interval of length h). The limit of the difference quotient (i.e., the derivative) is thus the instantaneous rate of change.
This tutorial is well understood if used with the difference quotient and the definition of the derivative. when this limit exists. Hence, to find the derivative from its definition, we need to find the limit of the difference quotient as h approaches zero. f(x) = m x + b.
