# Economics graphs

How would you draw graphs used to answer optimal consumption bundle questions in economics?

• Hello and welcome on TeX-SE. This kind of design is pretty common and you will find a bunch of examples to help you start. Come back with a specific question about what you struggled with, a Minimal Working Example of what you wrote already and you'll get some help, for sure. Jul 27 at 9:33

Something to start with, nothing fancy, just some try and error to draw the slope line. There are many ways to make a more customizable design but maybe that's not what you need yet.

\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{amsmath}
\usetikzlibrary{arrows.meta}

\begin{document}
\begin{tikzpicture}[>=Stealth]
\draw[thick,<->] (0,5) node[left]{$B$} |- (5,0) node[below]{$A$};
\draw[thick,blue] (0.3,5) to[bend right=40] node[pos=0.6,circle,inner sep=1pt,fill=black] (P){} (5,0.3) ;
\coordinate (O) at (0,0);
\draw[densely dashed] (P-|O) node[left]{$B^\star$} -| (P|-O);
\draw (P) --++ (142:2.9) node[left]{$\dfrac{I}{P_B}$};
\draw (P) --++ (-38:2.1) node[below]{$\dfrac{I}{P_A}$};

\draw[<-] (P) --++ (0.7,1.5) node[above]{\footnotesize Optimal bundle: $\dfrac{MU_A}{MU_B}=\dfrac{P_A}{P_B}$};
\end{tikzpicture}
\end{document}
