I am trying to position my images as follows. the problem is that the moment I delete the black point positioned at the origin, the positioning of my images are messed up.
My second question is that I went the images to blend with the text. Right Now it starts after the text but not inline with text. This is what I want to achieve.
this is my code:
\documentclass{beamer}
\usepackage{graphicx} % Allows including images
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables
\usepackage{comment}
\usepackage{listings}
\usepackage{hyperref,xcolor}
\usepackage{empheq}
\newcommand*\widefbox[1]{\fbox{\hspace{2em}#1\hspace{2em}}}

\usepackage{tikz}
\usetikzlibrary{calc,tikzmark,arrows,shapes,backgrounds}
\usepackage{xparse}% For \NewDocumentCommand
\usepackage{calc}% For the \widthof macro
\newcommand{\Text}{Lorem ipsum dolor sit amet, consectetur adipiscing elit.

\newcommand{\mytikzmark}[1]{\tikz[overlay,remember picture] \node[baseline] (#1) {};}

}{%
\coordinate (RightPoint) at (right.east);
}%
\draw[red,#2]
($(left)+(-0.2em,0.9em)$) rectangle
($(RightPoint)+(0.2em,-0.3em)$);}
}
\NewDocumentCommand{\DrawBoxWide}{s O{}}{%

% For every picture that defines or uses external nodes, you'll have to
% apply the 'remember picture' style. To avoid some typing, we'll apply
% the style to all pictures.

\begin{frame}{Surface Plots}
\begin{itemize}
\item It is more common to visualize surfaces in 3D
\item Example:
\begin{subequations}
\begin{empheq}[box=\widefbox]{align*}
&f(x,y)=sin(x)cos(y), \\
&x\in [-\pi , \pi]; y \in[-\pi ,\pi ]
\end{empheq}
\end{subequations}
\item \textcolor{orange}{\textbf{surf}} puts vertices at specified points in space x,y,z, and connects all the vertices to make a surface
\item The vertices can be denoted by matrices X\tikz[na] \coordinate (s-mat); ,Y\tikz[na] \coordinate (s-gray);,Z
\item How can we make these matrices
\begin{itemize}
\item loop (DUMB)
\item built-in function: \textcolor{orange}{\textbf{meshgrid}}
\end{itemize}
\end{itemize}
\tikzstyle{background grid}=[draw, black!50,step=.5cm]
\begin{tikzpicture}[show background grid]
\node [inner sep=0pt] (X) at (7,.50) {X};%\includegraphics[width=2cm]{X}
\node [inner sep=0pt](Y) at (9,1){Y};%\includegraphics[width=2cm]{Y}
% show origin
\fill (0,0) circle (2pt);
% define destination coordinates
\path (X) coordinate (mat)
(Y) coordinate (gray);
\end{tikzpicture}
\begin{tikzpicture}[overlay]
\path[->,black,thick] (s-mat) edge (mat);
\path[->,black,thick] (s-gray) edge (gray);
\end{tikzpicture}
\end{frame}

above is my desired result.
below is my actual output (after Sigur suggestion).

I used 2
\parboxes to insert side-by-side.
