The graph is one of the most widely used tools in **Microsoft Excel**. It helps to represent certain numeric values in a more presentable way. Along with the graphical representation, we also get various intersection points between the lines based on equations. In this article, we will learn how to find **graph intersection point** in **Excel **with **5 **useful methods.

## 5 Useful Methods to Find Graph Intersection Point

Here is a sample dataset to describe the methods. It shows the information on the **Demand **and **Quantity **of **Apple Products** and **Google Products** in the market. The values are placed in the **Cell range B6:C9 **and **E6:F9** respectively.

Now, we will create a graph and find the intersection point between the two graphical lines.

### 1. Manually Solve System of Equation to Find Intersection Point in Graph

When you have a quite simple dataset, you can manually solve the graph equation. As a result, you will find the intersection point between the lines. Letâ€™s see how it works.

- In the beginning, select the
**Cell range B6:C9**. - Then, go to the
**Insert**tab and choose**Scatter with Smooth Lines and Markers**chart type from the**Charts**section.

- As a result, you will get a single line graph based on the values like this.

- Now, right-click on the chart and choose
**Select Data**from its**Context Menu**.

- After this, select
**Add**in the new**Select Data Source**window.

- Following this, insert the
**Cell range E6:E9**as**Series X values**and**F6:F9**as**Series Y values**.

- Lastly, press
**OK**and you will get another line intersecting with the previous one in the graph. - From this graph, we can see that the lines have intersected in the
**coordinates (5,7)**.

- This is the easiest process to get intersection points. But if you have large and complex datasets, then the upcoming methods will be great for you.

### 2. Calculate Graph Intersection Point with Excel Solver

In this segment, we will use the **Excel Solver** tool to calculate the graphâ€™s intersection point. To do the task, follow the steps below.

- In the beginning, select the values of
**Demand**and**Quantity**of**Apple Products**. - Then, insert a
**Scatter**chart from the**Charts**section in the**Insert**tab.

- After this, enable
**Trendline**from the**Chart Elements**.

- Following this, right-click on
**Trendline**and select**Format Trendline**.

- Then, enable the
**Display Equation on chart**option under the**Trendline Options**.

- Similarly, follow the same steps for the
**Google Productâ€™s Demand**and**Quantity**. - As a result, you will get the following graph with equations.

- Now, based on the equations, we will find the intersection points.
- For this, separate the
**Variables**and**Constant**values like this.

- Next, insert this formula in
**Cell F5**which is a coefficient of the**1st****Basic Formula**.

`=E5*1+E6*1`

- Then, insert this formula as a coefficient of the
**2nd Basic Equation**in**Cell F6**.

`=E5*3+E6`

- At this stage, open
**Solver**under the**Analyze**section of the**Data**tab.

- Accordingly, insert
**Cell F5**in the**Set Objective**box. - Then, select
**Value of**and provide**12**as the value. - Along with it, insert the
**Cell range E5:E6**in the**By Changing Variable Cells**. - Following this, click on
**Add**to go to the next step.

- Now, insert
**Cells F6**and**G6**as the**Cell Reference**and**Constraint**respectively. - Also, select
**Equal**(**=**) as the condition.

- As a result, you will find the condition in the
**Subject to the Constraints**box. - Lastly, press
**Solve**on the**Solver Parameters**window.

- In the
**Solver Results**window, select**Keep Solver Solution**and hit on**OK**.

- Finally, you will get the coordinate values of the intersection point.

### 3. Combine INTERCEPT & SLOPE Functions to Show Graph Intersection Point

The combination of **the INTERCEPT** and **SLOPE functions** is a time saver to get intersection points. For this, go through these simple steps.

- First, insert this formula in
**Cell C11**.

- Then, press
**Enter**and you will get the**X Intercept**value.

- Afterward, type this formula in
**Cell C12**.

- Lastly, hit
**Enter**. - Thatâ€™s it, you will get the
**Y Intercept**value as well.

### 4. Determine Graph Intersection Point with Goal Seek Feature in Excel

**Goal Seek** is also a very useful tool in **Excel **to find the graph intersection point. For this, follow the steps below.

- In the beginning, make both equations equal based on the
**Y variable**. - Then, move them to the left-hand side of the equation resulting in
**0**on the right-hand side like this.

- Next, insert this formula in
**Cell E5**according to the new equation.

- Afterward, hit
**Enter**to see the preliminary value of the**Equation**.

- Along with this, insert
**0**as the**Result**according to the newly generated equation.

- Next, go to the
**Data**tab and select**What**â€“**If Analysis**.

- Here, choose
**Goal Seek**from the drop-down menu.

- After this, determine the parameters in the
**Goal Seek**dialogue box as shown below.

- Then, press
**OK**. - Lastly, hit on
**OK**again in the**Goal Seek****Status**window to confirm the solution found.

- Thatâ€™s it, we have got our
**X Intercept**in**Cell E7**.

- Also, insert this formula in
**Cell E8**based on the**2nd Basic Equation**.

- Finally, hit
**Enter**to get the**Y Intercept**as well.

### 5. Use Intersect Operator to Show Intersection Point

In this final method, letâ€™s use **Intersect Operator **to find intersection points from multiple columns and rows. When **2 ranges **are separated by a **Space **in the formula, they create an **Intersect Operator**. For illustration, here is a sample dataset with the quantity of **Apple Products**, **Google Products** and **Samsung Products** in the **Cell range B5:D9**.

Now, letâ€™s find out the intersection point among them.

- For this, simply insert this formula in
**Cell C10**.

- Following this, press
**Enter**. - Thatâ€™s it, we have got our required intersection points all at once.
