Autograph: How to force a linear best fit to go through (0,0)?

 

Here I have thrown on some points as data, selected it all and used “convert to data set”.
“y-on-x Regresion Line” does not pass through the origin.
To find the best fit straight line that does, enter “y = mx” and select it and the data set.
Use the right-click option “Best Fit” – this will find the value of ‘m’ that fits best.
