Slope Calculator (or Slope of a Line Calculator or Slope Formula Calculator) is an online tool to find slope of a line if coordinates of two points on the line are given.

This Calculator takes the co-ordinates of two points on the line as (x1, y1) and (x2, y2) and calculates the slope using the formula given below.

Slope of the line, m = $\frac{(y_{2} - y_{1})}{(x_{2} - x_{1})}$

 

Steps for Slope Formula

Back to Top
Step 1 :  

Apply the slope formula:  Slope (m) = $\frac{(y_{2} - y_{1})}{(x_{2} - x_{1})}$



Step 2 :  

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

  1. Determine the slope of a line, which contains the points A (4, 3), B (2, 1)?


    Step 1 :  

    The slope formula of the line is: Slope (m) = $\frac{(y_{2} - y_{1})}{(x_{2} - x_{1})}$


    Given x1 = 4, y1 = 3 , x2 = 2  and y2 = 1 .



    Step 2 :  

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


    So it will be = $\frac{(1 - 3)}{(2 - 4)}$. = $\frac{(-2)}{(-2)}$ = 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) = $\frac{(y_{2} - y_{1})}{(x_{2} - x_{1})}$


    Given x1 = -1, x2 = -2, y1 = -2 and y2 = 1.



    Step 2 :  

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


    So it will be = $\frac{(1 + 2)}{(-2 + 1)}$. = $\frac{3}{(-1)}$ = -3



    Answer  :  

    -3.
