IN A LINE GRAPH, IF A LINE IS STRAIGHT BUT THE DIAGONAL INSTEAD OF DOING THIS (/) IS DOING THIS (\) IS IT STILL INVERSELY PROPORTIONAL?
So basically, if a line on a line graph is going in a different direction, is it still inversely proportional?

Oh shit wait, it's a curve instead of a line, I can't remember what this means.
Fucking holiday assignments.

Isn't it just negative?
Plot your shit on wolfram alpha.

I don't know, it's the holidays, I'm not meant to remember what stuff is on the holidays. I have no fucking idea. The question is does it appear to show inverse variation. It looks something like this.

Just the Y value of the function.

Oh sorry the graph fucked up.
We had to set something to swing.
B) Plot these values on a graph, showing amplitude (A) on the vertical axis and number of 20-swing periods (n) on the horizontal axis.
C) Does your graph appear to show inverse variation? Write a sentence to explain why.

Yes, because X increases and Y decreases.
You can add some fancy words to make it look better.

Also, my friend said to ask this:
Does it have to decrease to a set factor
like halfing each time
or does one just have to decrease when one increaes
in order to be inversely proportional?

Actually, in order to be inverse, both factors have to change to inverse values (one increases while the other decreases).
So, if I got this straight, they don't have to decrease to X number in order to be inversely proportional, there's no set value for those kind of things, you can pick any value you want.

Well, yes.
That's inverse.
One goes up while the other goes down.
