OBJECTIVE 5
22
Using the data for the National League during the
2003 baseball season (table on next slide),
select two points and find an equation of the
line containing the points. Then graph the line
on the scatter diagram obtained in the example
using this data.
23
Choose any two points.

Using the data from the previous example
The slope of the line of best fit is 62.17, which
means that, for every 1 increase in the on-base
percentage, runs scored increase 62.17.
