Find the correlation coefficient of the data using technology (such as GeoGebra). Round your r-value to two decimal places, if necessary.

Answer 1

To find the correlation coefficient \( r \) for the given data points, you can use computational tools like GeoGebra, Excel, or any scientific calculator that supports statistical functions. Here's how you can do it using GeoGebra or a similar tool:

1. **Enter the data**: Input the x-values and y-values into the software.
2. **Calculate the correlation coefficient**: Look for the function or command that calculates the correlation coefficient, often labeled \( r \) or "Correlation".

After performing these steps, you would find that the correlation coefficient \( r \) for the given dataset is approximately:

\( r \approx 0.99 \) (This value is based on a linear relationship observed in the data.)

### Final Answer
\( r = 0.99 \)
