    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.

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.

economics graph

\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}
