@Amro I have the same problem to find the best fit line. Are you sure the answer is correct? I am not sure because I think if the best fit line is selected correctly, The number of points above the line must be equal to number of points under the line, Is it right?... 19/01/2010 · Re: Multiple best fit line I am plotting temp on y axis, time on x axis. pts are temps. Time starts with zero, .5, 1,1.5, 2, 2.5 and so on thru ten mins. equivalant temps are 50,43 40 37 34 33 28 27 25 23 20 19 18.5 18 18 17 17 16 15.5 15 15.

Add a new folder, name it, and add the following expressions below. Create 2 moveable points. Calculate the slope between them. Use the point/slope form of a line. how to deal with loneliness after a break up Mentor: A line of best fit is often useful to attempt to represent data with the equation of a straight line in order to predict values that may not be displayed on the plot. The line of best fit is determined by the correlation between the two variables on a scatter plot.
