Insert the following line just after \begin{tikzpicture}[...]

\clip (-.4,-.4) rectangle (4.1,2.1);

Use \shortstack with or without options 

\draw[axis] (0,0)  -- (3.2,0) node(xline)[below right]   
    {\emph{\shortstack{Independent\\ Variable}}};
\draw[axis] (0,0) -- (0,1.7) node(yline)[above] 
    {\emph{\shortstack{Dependent\\ Variable}}};

or

\draw[axis] (0,0)  -- (3.2,0) node(xline)[below right]   
    {\emph{\shortstack[l]{Independent\\ Variable}}};
\draw[axis] (0,0) -- (0,1.7) node(yline)[above] 
    {\emph{\shortstack[l]{Dependent\\ Variable}}};

which I prefere.

Best,
