添加\usepackage{tikz}到你的序言中。
然后在您想要的图形处插入以下代码。
\begin{figure}
\begin{tikzpicture}
%axis
\draw (12,0) -- (0,0)--(0,10);
% Blue lines
\draw[blue] (0,9)node[left]{\color{black}20} -- (11,0)node[below]{\color{ black}12}node[near end,right]{\color{black}$MC_2$};
\draw[blue] (0,9) -- (9,0)node[below]{\color{black}10}node[near end,left]{ \color{black}$MC_1$};
% Red lines
\draw[red] (0,1) -- (5,10)node[near end,right]{\color{black}$MB_1$};
\draw[red] (0,0.5) -- (8,10)node[near end,right]{\color{black}$MB_2$};
% Dotted lines
\draw[dotted,thick] (2.85,0)node[below]{$I^*$} -- (2.85,6.1)--(0,6.1)node[ left]{$U(I^*)$};
\draw[dotted,thick] (4.25,0)node[below]{$I$} -- (4.25,5.53)--(0,5.53)node[ left]{$U(I)$};
\draw (0,0)node[below]{0}node[left]{0};
\end{tikzpicture}
