<< I define slope as the change in y divided by the change in x >>
apart from the mathematical definitions stated, i also try, practically, to
define the slope as a measure of the instability of the relationship between
the two variables. if we "tweak" variable x, what happens to variable y, and
does it happen in any predictable fashion?
