  • The equation of the line of best fit is y = -4.75x + 88.571.
  • The correlation coefficient for the data that is shown is -0.906.

Step-by-step explanation:

  • The rate of change of one variable (y)  to the other (x) as a function is known as the regression coefficient.
  • A statistical measure of the relationship between the relative movements of the two variables is known as the correlation coefficient.

The equation of the line of best fit is y = -4.75x + 88.571 and the correlation coefficient r is -0.906.

y = ax + b    

a = -4.75

b = -88.571  

r² = 0.821  

r = -0.906

Answer:

Y=-4.75

+88.571

Correlation Coefficient: -0.906
