Finding the Line of Best Fit with Technology. We have learned how to fit a trend line to a scatter plot and find an equation of the trend line. In this activity we will use the calculator to perform both tasks. The trend line you will find with the calculator is called the . regression line. or . line of best. fit.

Prepare a scatter plot of the data. Using a strand of spaghetti, position the spaghetti so that the plotted points are as close to the strand as possible. Find two points that you think will be on the “best-fit” line. Calculate the slope of the line through your two points. Write the equation of the line. y – y1 = m(x – x1)
