# How to find rate of change on a graph?

**Finding the rate of change on a graph** can be tricky. In this post, we will learn various ways to find the rate of change on a graph. The examples given below are not just for education but also useful in real-life situations.

Let’s begin with an example. Suppose we have two variables on a graph like in the figure above. If we don’t know how much one variable increases as time passes or decreases as time passes, then it is difficult to analyze which variable increases at a slower speed and which variable increases at a faster speed. Let’s see some tips that can help solve this problem.

## How to find rate of change on a graph?

There are a few different ways to find the rate of change on a graph. One way is to find the slope of the line. To do this, you need to find two points on the line and then use the formula:

**rate of change m = (y2 – y1) / (x2 – x1)**

Finding the rate of change for a graph is a basic graphing skill that is often overlooked by both students and teachers. As there are multiple ways to determine the rate of change, below are some common methods to help you get started. To find the rate of change, first, identify the value at which you want to measure the rate of change.

For example, if you want to know the value of “x” at which the curve intersects with the y-axis, use an estimate of where this value is. Then, look at how “x” changes through time (i.e., observe how “x” changes over time).

Finally, divide by time to find the change in “x.” To do this, first divide by 1 to find the original x-value. Next, divide by 2 to find the halfway point in time interval. Finally, divide again by 2 to find the final x-value.

**Another way to find the rate of change is to use the graph** to find the average rate of change over a certain interval. To do this, you need to find two points on the graph and then take the average of the changes in y over the interval between those two points.

Whichever method you choose, make sure that you are using points that are close together on the graph so that the rate of change is accurate.

### Here’s an example of such a graph:

A graph can show us different things depending on the data and how it is plotted. In most cases, we want to see the trends of a series of values over time. For example, if you are selling used cars and you want to know how many people purchase your cars after they have been serviced. You would need to plot the number of cars sold over time so that you can track the same.
