I want to force this line to pass through zero, but i don't know how. I read about "Through zero" option, but i can not find it in my linear fit window... Is there another way? Thanks!

| Yes, I fixed intercept at zero, but the line still don't go through (0,0). Sorry, I didn't say what exactly i want... |

Hi sub.rosa,
Ah, you not only to get the formula with intercept=0, but also wanted to draw the fitted line visually goes thru (0,0), right?
Then, you can set the X range of the output fitted line, as shown below. You can set is as below. Also, after that, you may need to rescale the graph to show the origin.
