I have this picture


I draw with `pgfplots`. My code

	\begin{axis}[xmin=-1.1,xmax=5,ymin=-1.1,ymax=5,axis lines=center,
		xlabel=$x$, ylabel=$y$,
		\addplot[color=purple,thick,name path=upper] {(1-x/3)*4};
		\addplot[name path=lower] {5.2};
		\addplot[red,pattern=north west lines, pattern color=blue] fill between [of=upper and lower];
		\node[below left] at (0, 0) {$O$};
		\node[below left] at (1.5, 2) {$d$};

What is another way to draw this picture?
