Hi I want to draw this:

enter image description here

(letters and exact size don't matter)

my code is this but it doesn't work I want to mix these 2 lines here.

\subfigure
{
\begin{tikzpicture}[smooth,scale=0.8]
\draw[thick,->] (-2,0) -- (2,0) node[below] {$x$};
    \draw[thick,->] (0,-1.5) -- (0,1.5) node[right] {$y$};
    \draw[blue,thick,domain=0:1.5] plot (\x,{\x}) node[above]
    \draw[blue,thick,domain=-1.5:0] plot (\x,{0}) node[above]
\end{tikzpicture}
}
\subfigure

thanks for your helps.
