The steepness of a straight line gives the rate of change or slope. It tells us at what extent the straight line varies in the graph and is denoted by m.
Rate of Change
It is calculated if the coordinates of end points (x1, y1) and (x2, y2) of the line are given by the formula
Rate of Change Formula
Rate of Change Calculator is a online tool to calculate the slope of the straight line if the coordinates of end points (x1, y1) and (x2, y2) are given. It makes the calculation easier and fun full.
Here are the Steps for finding the Rate of change

Step 1 :
Read the given problem and observe the end points (x1, y1) and (x2, y2).

Step 2 : The slope formula is given by
                                m = $\frac{y_2 - y_1}{x_2 - x_1}$

Plug in values of (x1, y1) and (x2, y2) in the above formula and get the answer.
