Can you force a line of best fit to go through the origin?
This is, no force, no extension. Such a relationship expressed graphically MUST pass through the origin. Because of errors in the collected data, a linear fit will almost never pass through the origin as it should. The way to solve this problem is to conduct a proportional fit, y = mx.
Does a trend line have to go through the origin?
The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.
