Main Question or Discussion Point

Hello, I am trying to remove the y-intercept from my linear fit with this software since my equation is y=mx and NOT y=mx+b, so I need to figure out how to remove the y-intercept so my data will have a smaller % error, because the intercept makes the slope larger than it should be. Any ideas how to do this? (yes I checked online, tutorial, help menu, etc)!!

Do an analysis that gives a parameter estimate for the intercept for a simple linear regression of y against x, and then subtract that value from all the y-values and re-do the regression with these new ones.
