They are proportional if a change in one of the quantities always and necessarily results in a proportional change in the other.
So if you think of a simple equation, x = 2y then the quantities are proportional. If you double y then x is necessarily also doubled. If you triple y then x is also tripled. If you halve y then x is halved and so forth.
However x = 2y + 1 is non proportional. This is because if, for example, you double y then x is increased but it is not exactly doubled and so the change is not in proportion. For example, in this equation, when y = 2 then x = 5. When y = 4 then x = 9. 9 is not the double of 5.

What makes two quantities proportional?
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
