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

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.

## Examples on Slope Formula Calculator

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

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

-3.
