### Instructions

Use a graphing calculator to create a scatter plot and find the line of best fit and the correlation coefficient for the following data. Round to the nearest hundredth.

### Data Table

| x  | y  |
|----|----|
| 2  | 2  |
| 4  | 3  |
| 6  | 6  |
| 8  | 7  |
| 10 | 10 |
| 12 | 15 |
| 14 | 19 |

### Steps to Follow

1. **Create a Scatter Plot:**
   - Input the x-values and y-values into the graphing calculator.
   - Plot each (x, y) point on a coordinate grid.

2. **Find the Line of Best Fit:**
   - Use the calculator's linear regression function to determine the equation of the line of best fit.

3. **Calculate the Correlation Coefficient:**
   - The calculator will also provide the correlation coefficient (denoted as 'r'), which indicates how well the line fits the data.

4. **Round Results:**
   - Ensure that all numerical results, including the slope, intercept, and correlation coefficient, are rounded to the nearest hundredth.
