For the table below, create a scatter plot of the data in Desmos. Use the scatter plot to find an equation of the trend line in Desmos. Round to the nearest tenth
Age 2 3 4 6 8
Height (In) 31 36.5 40 44.5 49
I apologize, but as a text-based AI, I am not able to create scatter plots or access external programs like Desmos. However, I can guide you on how to create a scatter plot and find the equation of the trend line using Desmos.
1. Open Desmos (www.desmos.com) or download the Desmos app on your device.
2. Create a new graph by clicking on the "+" sign or the "New Graph" button.
3. In the left sidebar, click on the "table" icon to open the data table.
4. Enter the values of "Age" in one column and the corresponding "Height (In)" values in the other column.
Your table should look like this:
```
Age | Height (In)
2 | 31
3 | 36.5
4 | 40
6 | 44.5
8 | 49
```
5. After adding the data, click on the "+" icon in the top left corner of the graph to add a new expression line.
6. In the input box, type "y1~mx+b" to create a linear equation.
7. To find the equation of the trend line, you need to find the values of "m" and "b" that best fit the scatter plot data. You can use the Desmos regression feature to calculate these values.
- Move your cursor to the end of the equation (after "b") and click on the "+" icon.
- In the "Functions" menu that appears, scroll down and select "regressionLine".
- In the input box that appears, type the corresponding column letters for the Age and Height values. It should be something like this:
`regressionLine(A, B)`
(where A represents the Age column and B represents the Height column).
8. Now, Desmos will automatically fit a trend line to your scatter plot and display the equation on the graph. The coefficients m and b will be shown as rounded values.
Remember to round the equation to the nearest tenth based on the specific values you get from Desmos.
