question
use the data tab of the graphing tool to display the data from luther’s table in a scatter plot, with x representing the number of pitches thrown and y representing the average speed of the pitches. select the relationship tab to add the best fit linear function to the graph.
what are the equation of the line of best fit and the absolute value of the correlation coefficient?
line of best fit ( y = -0.511x + 91.636 )
|correlation coefficient| = 0.9672

Explanation:

Step1: Identify the line of best fit equation

From the given data, the line of best fit is provided as \( y = -0.511x + 91.636 \).

Step2: Identify the absolute value of correlation coefficient

The absolute value of the correlation coefficient is given as \( |\text{correlation coefficient}| = 0.9672 \).

Answer:

The equation of the line of best fit is \( y = -0.511x + 91.636 \) and the absolute value of the correlation coefficient is \( 0.9672 \).
