Well I know Direction Proportionality has a cut-off infinity symbol to represent it, but the Inverse Proportionality does not have a symbol and instead is just written out. Why is that? Wouldn't it be so much easier to have a single symbol for it?

I'm just screwing around with concepts right now and writing them out for notes, and I feel like a couple screws popped loose in my head when I found out I can't just slap an Inverse Proportional symbol down because there isn't any!

I think I'm just gonna be a rebel and put a " - " in front of my Direct Proportional symbol regardless, but I need to know... why isn't there a symbol for it?

Because if x is inversely proportional to y, you can just say x ∝ 1/y.

Direct proportionality:
y ∝ x

Inverse proportionality:
y ∝ (1/x)

Problem solved.
Ok, not entirely.

Consider this:
y=x has a symbol
but
y=-x
doesn't have an individual symbol.
what about
y=(1/x)
And
y =-(1/x)


We only need one relational symbol for that.
