Call the surface $\"+y+=+0+\"$
\n" ); document.write( "Call $\"+97+\"$ m below the surface $\"+y+=+-97+\"$
\n" ); document.write( "and $\"+t+=+0+\"$ where $\"+t+\"$ is time in minutes
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "Plot $\"+y+\"$ on the vertical axis
\n" ); document.write( "Plot $\"+t+\"$ on the horizontal axis
\n" ); document.write( "-------------------------------
\n" ); document.write( "The rate of change of the diver's depth is
\n" ); document.write( "a positive $\"+5+\"$ m/min
\n" ); document.write( "-------------------------------
\n" ); document.write( "The linear equation for the diver is:
\n" ); document.write( " $\"+y+=+5t+-+97+\"$
\n" ); document.write( "Notice that when $\"+t=0+\"$ , $\"+y+=+-97+\"$
\n" ); document.write( "as it should
\n" ); document.write( "------------------------------------
\n" ); document.write( "When $\"+t+=+10+\"$ min
\n" ); document.write( " $\"+y+=+5%2A10+-+97+\"$
\n" ); document.write( " $\"+y+=+50+-+97+\"$
\n" ); document.write( " $\"+y+=+-47+\"$
\n" ); document.write( "The diver is 47 m below the surface
\n" ); document.write( " \n" ); document.write( "

\n" );
