Rate of Change Calculator is an online tool to calculate slope of a line if coordinates of end points of line is given. It makes calculation easy and fun. If coordinates of end points of a line is given then it can easily find the rate of change or slope of that line.
 

Steps for Rate of Change

Back to Top
Step 1 :  

Apply the formula for slope equation.


Slope (m) =$\frac{(y2 - y1)}{(x2 - x1)}$  [since rate of change is equal to slope of the equation]



Step 2 :  

Plug in the 'x1,x2' and 'y1,y2' values in the formula for the desired result.



Examples on Rate of Change

Back to Top
  1. Find rate of change of the given points A (4, 3), B (2, 1)?


    Step 1 :  

    The slope formula of the line is: Slope (m) = $\frac{(y2 - y1)}{(x2 - x1)}$


    Here x1=4, y1=3 , x2=2 , y2=1 .



    Step 2 :  

    Slope = $\frac{(1 - 3)}{(2-4)}$.


    = $\frac{-2 }{-2  }$


    = 1



    Answer  :  

    1



  2. Determine the slope of a line, which contains the points A (-1, -2), B (-2, 1):


    Step 1 :  

    The slope formula of the line is: Slope (m) = $\frac{(y2 - y1)}{(x2 - x1)}$.


    Here x1 = -1, x2 = -2, y1 = -2, y2 = 1.



    Step 2 :  

    slope = $\frac{(1 +2 y1)}{(-2 +1)}$


    = $\frac{3}{-1}$


    = -3



    Answer  :  

    -3.
