I want to graph $E=mc^2$ on a graphing calculator but I am unsure how to format the equation to work; it's been $15$ years since I messed with graphs.

1Replace $m$ with $x$, $e$ with $y$. So graph $y = c^2 x$, which is a linear function in the variable $x$ (i.e., mass). (Remember: $c$ is constant.) – Mark Twain Apr 23 '17 at 20:09

1Actually, why would you want to graph that? – Hagen von Eitzen Apr 23 '17 at 20:12

@HagenvonEitzen I was thinking the same thing. :) – Mark Twain Apr 23 '17 at 20:12

Just for me :). I can't post an image of the graph I want it to look like I don't have enough rep :/ – Matt Apr 23 '17 at 20:14

1Just for your information, graphing $e=mc^2$ might sound cool but is pretty useless in practice – Apr 23 '17 at 20:20

@MatthewLozoya If you can't post an image directly, then you could put one on imgur (for example) and give us the link. That might help explain what you're after. – Théophile Apr 23 '17 at 22:33

As others have pointed out, this equation is just a straight line passing through the origin, since $c$ (the speed of light) is constant. It looks like this (where $y=E$ and $x=m$):
