How can I indicate a positive relationship between two things? As one goes up, the other goes down?

Question

Is there some kind of math symbol? Or would greater than/less than be appropriate?

Answer 1

Greetings,

The symbol 'α' means proportional to

Suppose as x increases y decreases,

then we can write

x α 1/y

or x = k/y where k is some constant found by graphing

Regards

Answer 2

You are describing an "inverse" relationship. You might indicate it this way:

X:1/Y (X is proportional to the inverse of Y)

Answer 3

You can't. There is no such thing as absolute motion, it is all relative.
