# Deducing the axis of a graph if given equation is gradient Watch

1. Hello everyone,
So I've been given an equation Y=1/2gpr(h+r/3)
ive been trying to rearrange it in order to allow me to get the gradient of a graph as Y but to no avail. I tried putting the equation squared on the y axis and the equation on the x axis and they therefore will cancel (if I'm right) but that seems wrong.
thanks a lot, any help would be greatly appreciated

Right, OK. This seems fun. Is it just the equation of a line or does it bear any relevance?
5. It was a physics question but we were basically told that there were no unknowns in the questions I.e nothing is missing. I didn't actually get given any values its just a theoretical thing so the y axis divided by the x axis must equal y which is given by that equation. It seemed stupid to me given the fact that there are no unknowns... Any help would be greatly appreciated
6. It's Y= one half (GPR) TIMES (h+ one third R) I'm not sure how to write it down propery on the web

How do you find the gradient of a line?
12. Y/X, so would equation squared on y and equation on x work?

In theory - however just take a look at the equation I posted for a minute - what do you notice about it?

It's double y? Sorry I'm not very good at maths so I'm probably missing something obvious

Well from what you said your equation is a half of GPR, which is then multiplied by h+r/3, correct?

Absolutely correct
18. If I've done it right that can be represented by the equation I gave

Absolutely correct

Thank you +rep

Thank you +rep
I can't guarantee it's correct but it's what I'd use
