Here's a graph:
\n" ); document.write( " $\"+graph%28+600%2C+600%2C+-200%2C+200%2C+-12000%2C+4000%2C+80x+-+7500+%29+\"$
\n" ); document.write( " $\"+d%28m%29+=+-7500+%2B+80m+\"$
\n" ); document.write( "The graph is easy to make
\n" ); document.write( "Pick a value for $\"+m+\"$ , like m = 0, 10, 20, 30, 40, 50, etc
\n" ); document.write( "Find $\"+d%28m%29+\"$ for each pick
\n" ); document.write( "For instance:
\n" ); document.write( " $\"+m+=+50+\"$
\n" ); document.write( " $\"+d%2850%29+=+-7500+%2B+80%2A50+\"$
\n" ); document.write( " $\"+d%2850%29+=+-7500+%2B+4000+\"$
\n" ); document.write( " $\"+d%2850%29+=+-3500+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "Note that $\"+d%28m%29+=+0+\"$ gives me
\n" ); document.write( " $\"+0+=+-7500+%2B+80m+\"$
\n" ); document.write( " $\"+80m+=+7500+\"$
\n" ); document.write( " $\"+m+=+93.75+\"$
\n" ); document.write( "This is $\"+m+\"$ for sea level
\n" ); document.write( "Any value of $\"+m+\"$ greater than $\"+93.75+\"$
\n" ); document.write( "and likewise, any $\"+d%28m%29+\"$ greater than $\"+0+\"$ is
\n" ); document.write( "meaningless since a submarine can't fly
\n" ); document.write( " \n" ); document.write( "

\n" );
