Let us assume that we have a graph created by a program different from LaTeX (that is not with PStricks or Tikz). I was wandering if it is possible to incorporate mathematical symbols on that graph using a TeX editor.
Thank you.

Basically, this is using the example of the stackengine documentation, adapted for use in math mode with the addition of \stackMath in the preamble.
The routine you want is \stackinset which has 6 arguments, \stackinset{H-anchor}{H-offset}{V-anchor}{V-offset}{inset}{underlying anchor image}. As shown here, it can be nested and the insets themselves can be stacks.
\documentclass[standard]{letter}
\usepackage[usestackEOL]{stackengine}
\stackMath
\usepackage{graphicx}
\def\imgi{\includegraphics[width=.75in]{example-image}}
\begin{document}
\stackinset{l}{ .1in}{b}{.2in}{y=mx+b}{%
\stackinset{r}{ .1in}{t}{.2in}{\Longstack{F_x=ma_x\\F_y=ma_y}}{%
\stackinset{c}{-.5in}{c}{.4in}{E=mc^2}{%
\stackinset{r}{ .8in}{b}{.6in}{\psi^2=0}{%
\stackinset{r}{ .1in}{c}{.0in}{\imgi}{%
\includegraphics[width=3in]{example-image}%
}}}}}
\end{document}

1@cmhughes I specifically said that I want to manipulate a graph not made by PStricks or Tikz. Commented Apr 14, 2014 at 18:55

3@PantelisKazakis: The linked question is about drawing on an image... and that's that. That image could have been made using PStricks, TikZ, a camera, or whatever...– Werner ♦Commented Apr 14, 2014 at 19:02

@Werner I will follow Steve's way. It is quite neat! Commented Apr 14, 2014 at 19:03
\stackinsetfrom thestackenginepackage. See page 20 of the documentation in stackengine.pdf at ctan.org/tex-archive/macros/latex/contrib/stackengine.epsfile and there is some text in this graph file, the text can be replaced fromLaTeXusing the\psfragcommand from the corresponding package, but this collides with pdflatex nowadays a little bit
