Simplistically, it means that as one side of an equation increases/decreases, the other side moves in the same direction.....a good example is the conversion of the Centigrade scale to the Fahrenheit scale, thusly:
F = (9/5) C + 32
Note, as "C" increases/decreases, "F" exhibits the same behavior.....
