May be some thing like this:

\documentclass{article}
\usepackage{colortbl}
\usepackage{arydshln,graphicx,xcolor,array}

\begin{document}
  \arrayrulecolor{magenta}%
  \setlength{\arrayrulewidth}{1pt}%
  \begin{tabular}{c;{2pt/2pt}c|}
    \includegraphics[width=3cm]{example-image-a} & \includegraphics[width=3cm]{example-image-b}
  \end{tabular}
  \arrayrulecolor{blue}%
  \setlength{\arrayrulewidth}{1pt}%
  \begin{tabular}{c;{2pt/2pt}c}
    \includegraphics[width=3cm]{example-image-a} & \includegraphics[width=3cm]{example-image-b}
  \end{tabular}

\end{document}

If you don't mind using tikz, you may use matrix library of tikz and draw the lines in any way you like. This method is highly versatile.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}

\begin{document}

\begin{tikzpicture}
\matrix (a)[row sep=0mm, column sep=0mm, inner sep=1mm,  matrix of nodes] at (0,0) {
            \includegraphics[width=3cm]{example-image-a} &
            \includegraphics[width=3cm]{example-image-b} &
            \includegraphics[width=3cm]{example-image-c}\\
            \includegraphics[width=3cm]{example-image-a} &
            \includegraphics[width=3cm]{example-image-b} &
            \includegraphics[width=3cm]{example-image-c}\\\\
        };
%

\draw[thick,red] (a-1-1.north east) -- (a-2-1.south east);
\draw[thick,densely dashed,blue] (a-1-2.north east) -- (a-2-2.south east);
\end{tikzpicture}

\end{document}

May I suggest an alternative. Use algorithmic package where you can find more information here Algorithms. Two images are generated: one from your code, the other is an example based on OP image.

\documentclass[10pt,a4paper]{article}
\usepackage{algorithmic}
\usepackage{algorithm}
\begin{document}

% Your code

\noindent\rule[0.5ex]{\linewidth}{1pt}
Algorithm Use iteration to find general solution

\noindent\rule[0.5ex]{\linewidth}{1pt}

factor $a$,$b$

$y=a+bx$

\noindent\rule[0.5ex]{\linewidth}{1pt}

% alternative

\begin{algorithm}
\caption{Use iteration to find the general solution of the ODE in Example 1.4}\label{abc}
\begin{algorithmic}[1]
\STATE factor \textbf{a,b};
\STATE {\textbf {y:=a+b*x}};
\FOR {\textbf{n:=1:4 do write}}
\STATE {\textbf{y:=a+b*x-int(int(y,x),x)}}
\ENDFOR
\end{algorithmic}
\end{algorithm}
\end{document}

TikZ Diagrams – Draw Angle with Label Between Lines

You can use the angles library which defines a pic for this purpose. The quotes library is used for ease of labelling.

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{calc,patterns,angles,quotes}
\begin{document}
  \begin{tikzpicture}
    \coordinate (origo) at (0,0);
    \coordinate (pivot) at (1,5);

    % draw axes
    \fill[black] (origo) circle (0.05);
    \draw[thick,gray,->] (origo) -- ++(4,0) node[black,right] {$x$};
    \draw[thick,gray,->] (origo) -- ++(0,-4) node (mary) [black,below] {$y$};

    % draw roof
    \fill[pattern = north east lines] ($ (origo) + (-1,0) $) rectangle ($ (origo) + (1,0.5) $);
    \draw[thick] ($ (origo) + (-1,0) $) -- ($ (origo) + (1,0) $);

    \draw[thick] (origo) -- ++(300:3) coordinate (bob);
    \fill (bob) circle (0.2);

    \pic [draw, ->, "$\theta$", angle eccentricity=1.5] {angle = mary--origo--bob};
  \end{tikzpicture}
\end{document}

marked angle

If you want the angle in red with two-way arrows, just modify the last line:

\pic [draw=red, <->, "$\theta$", angle eccentricity=1.5] {angle = mary--origo--bob};

modified marked angle

EDIT (Respond to query in comments)

To change the colour of the label as well, just set the text key:

\pic [draw=red, text=blue, <->, "$\theta$", angle eccentricity=1.5] {angle = mary--origo--bob};

modified modified marked angle
