Answer: 9 points
Step-by-step explanation:
The coefficient of determination is a number between 0 and 1 used to measure the level of precision with which the regression model created fits the data. A measure of [tex]R ^ 2 = 1[/tex] means that the model explains the entire variation between the two variables without error.
Therefore, in this case if [tex]R ^ 2 =1[/tex] means that the 9 points are on the line
