He wants to know whether there's a relationship between his average velocity and the number of pitches he throws. So, he recorded data from his last six games and organized it into this table.

Question
Use the data tab of the graphing tool to display the data from Luther's table ina 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?
