In this tutorial we discuss the derivative of linear function or derivative of straight line equation in the form of slope intercept.
Let us suppose that linear function of the form where is slope and is Y-intercept represents the equation of straight line.
Differentiating the given linear function with respect to , we get
In the given function we have two values, now differentiate separately we get
Using the following formulae and to evaluate given function as
We concluded that the derivative of given function is the slope of function.
Example: Find the derivative of
We have the given function as
Differentiation with respect to variable , we get
Now using the formulas and , we have
