For a set of data, x is the explanatory variable.Its mean is 8.2, and its standard deviation is 1.92.

For the same set of data, y is the response variable. Its mean is 13.8, and its standard deviation is 3.03.

The correlation was found to be 0.223.

Select the correct slope and y-intercept for the least-squares line.

  • Slope = -0.35

y-intercept = -10.9

  • Slope = -0.35

y-intercept = 10.9

  • Slope = 0.35

y-intercept = -10.9

  • Slope = 0.35

y-intercept = 10.9
