# Estimate effect on mean of dependent variable of an increase in the independent variable in a linear regression

Suppose I have the linear regression equation:

Y = B0 + B1(x)

How do I find the estimated effect on mean Y of an additional 50 to x?

I believe this is the multiplicative effect.

I think that this is obvious: if you have an equation y = b0 + b1x and x increased by 50, then y' = b0 + b1(x + 50).
So y' - y = b1 * 50
