Graphing interpretation

What would it mean if the line of a linear regression graph went through the origin?

If it doesn't go through the origin and I make it go through the origin, what am I doing?

I was looking for the answer to this and all I came up with was that if the line goes through the origin, then the data obtained, conforms to the ideal.
As for what I'm doing when I alter the line to go through the origin, I don't know about that.

Thank you

  • Graphing interpretation -

    If it goes through the origin, you have a direct relationship. y=kx

    If you alter it to go through the origin, and it doesn't , you are fudging data is all I can think.
