Why Should the Line of Best Fit for a Spring Constant Lab Pass Through (0,0)?

[APysics]

Homework Statement

we did a spring constant lab in school, we took a hanging spring and added weights to it, measuring displacement with each new weight. we were then instructed to create a graph and find the slope. i did that. then we were instructed to find the line of best fit. my line was linear. then the instructor as asked us a question about the graph: does it make sense that your line of best fit for your data pass through (0,0)? why or why not??

Well, since you have a graph drawn out. And you obtained a straight line, the relationship between the 2 variable must be Y=mX+C.

What is your Y, m,X and C?

Does it look like certain formula you have seen before?
