document.write( "Hi,
\n" );
document.write( "So good to hear you are using www.padowan.dk/graph 
\n" );
document.write( "To get an accurate look at the slope, one need to use the same range for x and y.
\n" );
document.write( "In order to see where the line crosses the x-axis, am using the range -300,300 for both x and y-values of the Axes.
\n" );
document.write( "P = .15x -28    || As in y = mx + b, where m is the slope and b the y-intercept
\n" );
document.write( "m = .15
\n" );
document.write( "
\n" );
document.write( "If one uses for ex -100, 100 for the y-values, that's ok ... just that then the
\n" );
document.write( "graph at first glance appears to say y is increasing 'faster' so to speak.
\n" );
document.write( "
\n" );
document.write( "As to Your other questions: You did not say if P represents profit in 1000s?
\n" );
document.write( "Many times that is used.  or if x represents how many thousands are made...
\n" );
document.write( "One needs to know what exactly the x and P represent
\n" );
document.write( " \n" );
document.write( "

\n" );
