- 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.
<u>Step-by-step explanation</u>:
- 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
