## How to Use the Rate of Change Calculator?

The procedure to use the rate of change calculator is as follows:

Step 1: Enter the X and Y coordinate points in the given input field. I.e., (x1, y1) and (x2, y2)

Step 2: Now click the button “calculate Rate of Change” to get the output

Step 3: The result will be displayed in the output field

### What is the Rate of Change?

A rate of change defines how one quantity changes in relation to another quantity. The rate of change can be either positive or negative. Since the slope of a line is the ratio of vertical and horizontal change between two points on the plane or a line, then the slope equals the ratio of the rise and the run.

Where,

Rise is the vertical change between two points

Run is the horizontal change between two points

### Standard Formula

The standard form for the rate of change of slope, m is given by

Rate of change = Rise/ Run

= Δy / Δx

Therefore, the rate of change of slope =(y2 – y1) / (x2 – x1)

Where

Δ represents the rate of change

(x1, x2) is the X coordinates

(y1, y2) is the Y coordinates

## Frequently Asked Questions on Rate of Change Calculator

### What is meant by slope?

The slope represents the gradient of the line. It is denoted by the symbol “m”. It defines the rate of change.

### Can a slope be negative?

A slope can be either positive or negative. If a line has a positive slope (i.e., m > 0), then y always increases when x increases and y always decreases when x decreases. Also, if a line has a negative slope (i.e., m<0), then y always increases when x decreases and y always decreases when x increases.

### What is the formula for the slope?

The formula to find the slope is

m = (y2 – y1) / (x2 – x1)

Where

(x1, x2) is the X coordinates

(y1, y2) is the Y coordinates
