business and finance interest rates# What is the rate of change in a graph?

Last Updated: 10th March, 2020

**rate of change**from

**graph**. The

**rate of change**is the

**rate**at which y-values are

**changing**with respect to the

**change**in x-values. To determine the

**rate of change**from a

**graph**, a right triangle is drawn on the

**graph**such that the line of the

**graph**is the hypothenuse of the right triangle.

Keeping this in consideration, what is the rate of change?

A **rate of change** is a **rate** that describes how one quantity **changes** in relation to another quantity. If x is the independent variable and y is the dependent variable, then. **rate of change**=**change** in y**change** in x.

Similarly, how do I find the average rate of change? The units on a **rate of change** are “output units per input units.” The **average rate of change** between two input values is the total **change** of the function values (output values) divided by the **change** in the input values.

Also to know, how do I calculate rate of change?

For an **estimation** of the instantaneous **rate of change** of a function at a point, draw a line between two points ("reference points") very close to your desired point, and determine the slope of that line. You can improve the accuracy of your **estimate** by choosing reference points closer to your desired point.

What is a unit rate?

**Rates**. When **rates** are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called **unit rates**. If you have a multiple-**unit rate** such as 120 students for every 3 buses, and want to find the single-**unit rate**, write a ratio equal to the multiple-**unit rate** with 1 as the second term.
