Microsoft Excel is a powerful software. We can perform numerous operations on our datasets using Excel tools and features. There are many default Excel Functions that we can use to create formulas. Many educational institutions and business companies use Excel files to store valuable data. Sometimes, we insert charts or graphs because they represent survey results better. Again, we carry out mathematical tasks with equations in an Excel worksheet. Plotting a chart without having the prior dataset may seem a complicated job. This article will show you the step-by-step procedures to graph an equation in Excel without data.

## How to Graph an Equation in Excel Without Data: with Easy Steps

You can use any mathematical equation as per your wish. In this example, weâ€™ll use the simple linear equation: **y = mx + c**. This equation will return straight lines when plotted on a graph. Here, **x **is an independent variable whereas, the **y **variable depends on **x**. And **c **is a constant, known as the intercept of **y**. Lastly, **m **is the gradient, also known as the slope of the straight line. So, weâ€™ll graph the equation without having a dataset beforehand. Therefore, go through the following steps carefully to perform the task.

### STEP 1: Input Equation

In our first step, weâ€™ll input the equation.

- For that purpose, type
**m**,**x**,**c**, and**y**in the cell range**B4:E4 respectively.** - See the below picture for a clear understanding.

### STEP 2: Apply Formula for Calculation

However, we need to create a simple formula for the **y **variable calculation. Here, weâ€™ll create that formula. Hence, follow the process to perform the task.

- Now, in cell
**E5**, type the formula:

`=(B5*C5)+D5`

- Next, press
**Enter**. - Itâ€™ll return
**0**for now as weâ€™re yet to enter the cell values.

### STEP 3: Graph Equation

This is the most important step. Weâ€™ll insert a graph in this step. So, learn the process to carry out the operation.

- Firstly, select the range
**C4:C9**. - Then, press and hold down the
**Ctrl key.** - After that, select the range
**E4:E9**. - The following figure will make it clear for you.

- Subsequently, go to the
**Insert tab.** - There, click
**Recommended Charts**.

- As a result, the
**Insert Chart**dialog box will pop out. - Go to the
**All Chart tab.** - Next, press
**X Y (Scatter)**. - Consequently, choose
**Scatter with Smooth Lines and Markers**. - Afterward, press
**OK**.

- Thus, youâ€™ll get the graph.
- But as we have an empty dataset, you wonâ€™t see any plottings for now.

### STEP 4: Input Data

Weâ€™ll also show how to input data after weâ€™re done with the graph insertion.

- First of all, place the value of
**m**as**2**for all the cases. - Then, type your desired values for the independent variable
**x**. - Similarly, insert the value of
**c**as**5**. - Finally, apply the
**AutoFill**tool to get the outcomes of the range**E5:E9**. - Hence, itâ€™ll return the accurate outputs for the
**y variable.** - Look at the below dataset to realize better.

### Final Output

As a result, youâ€™ll automatically see a linear line graph as shown below. So in this way, we can graph an equation without having the dataset. This is applicable to any equation.
