How to graph equations in math IT?
<p>I found this library (<a href="http://math-it.org/index.html" rel="nofollow">http://math-it.org/index.html</a>) but no examples so as not to use it. I want to do is to plot an equation (2x +5 = 50). 
So any example or explanation is very helpful.
Thank you.</p>
