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

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

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

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
