To find the correlation coefficient (r-value) of the given data, you would typically input the x and y values into a statistical software or tool like GeoGebra, Excel, or a graphing calculator. However, I can help you derive the correlation coefficient manually based on the data.

The data provided is:

  • (5, 22)
  • (6, 29)
  • (7, 28)
  • (8, 31)
  • (9, 37)

Using statistical calculations or software (like GeoGebra), you can find the correlation coefficient.

Based on typical calculations or results from statistical software:

The correlation coefficient is approximately 0.94.

Therefore, the answer is 0.94.
