Interpreting b1*X

May sound silly question, How do you interpret b1*X in statistical language, I mean what does it indicate?

It’s the beta coefficient on the output of a regression model. It scales any value of X you input to produce a value that is a close estimation to what the dependent variable would be if it wasn’t estimated.

Thanks for the perfect statistical interpretation but I should’ve asked for simpler version…Can you simplify further?
