Often you may be interested in plotting an equation or a function in Excel. Fortunately this is easy to do with built-in Excel formulas.

This tutorial provides several examples of how to plot equations/functions in Excel.

**Example 1: Plot a Linear Equation**

Suppose you’d like to plot the following equation:

**y = 2x + 5**

The following image shows how to create the y-values for this linear equation in Excel, using the range of 1 to 10 for the x-values:

Next, highlight the values in the range **A2:B11**. Then click on the **Insert **tab. Within the **Charts **group, click on the plot option called **Scatter**.

The following plot will automatically appear:

We can see that the plot follows a straight line since the equation that we used was linear in nature.

**Example 2: Plot a Quadratic Equation**

Suppose you’d like to plot the following equation:

**y = 3x ^{2}**

The following image shows how to create the y-values for this equation in Excel, using the range of 1 to 10 for the x-values:

Next, highlight the values in the range **A2:B11**. Then click on the **Insert **tab. Within the **Charts **group, click on the plot option called **Scatter**.

The following plot will automatically appear:

We can see that the plot follows a curved line since the equation that we used was quadratic.

**Example 3: Plot a Reciprocal Equation**

Suppose you’d like to plot the following equation:

**y = 1/x**

The following image shows how to create the y-values for this equation in Excel, using the range of 1 to 10 for the x-values:

Next, highlight the values in the range **A2:B11**. Then click on the **Insert **tab. Within the **Charts **group, click on the plot option called **Scatter**.

The following plot will automatically appear:

We can see that the plot follows a curved line downwards since this represents the equation y = 1/x.

**Example 4: Plot a Sine Equation**

Suppose you’d like to plot the following equation:

**y = sin(x)**

The following image shows how to create the y-values for this equation in Excel, using the range of 1 to 10 for the x-values:

Next, highlight the values in the range **A2:B11**. Then click on the **Insert **tab. Within the **Charts **group, click on the plot option called **Scatter with Smooth Lines and Markers**.

The following plot will automatically appear:

**Conclusion**

You can use a similar technique to plot any function or equation in Excel. Simply choose a range of x-values to use in one column, then use an equation in a separate column to define the y-values based on the x-values.
