8/09/2018 · Determine the slope of the line-of-best-fit through the data points. To calculate the slope of the line you take rise divided by run. Using two of your data points, subtract the X- and Y-values from each other, then divide Y/X. The equation for the slope of a line is (Y 2 - Y 1)/(X 2 - X 1). The point higher on the line is given the subscript 2, while the lower point is given the subscript 1

How do you find a line of best fit? Yahoo Answers

To help with the predictions you can draw a line, called a best-fit line that passes close to most of the data points. Approximately half of the data points should be below the line and half of the points above the line. If the data points come close to the best-fit line then the correlation is said to be strong.
