Since w > 45, the slope of the line must be > 1. Hence the Y coordinate, will be greater than the X coordinate, when both are positive. Hence 2m<n+m

Another way of thinking about this is to set up an function with a positive slope.

For instance f(x)= 2x

For every positive x value one enters, y will always be greater.


EDIT: Sorry, mixed up A and B in my answer
