document.write( "Hi,
\n" );
document.write( "the standard point-slope form for an equation of a line y = mx + b  where m is the slope and b the y-intercept.  
\n" );
document.write( "5x+4y-20=0   Solving for 'y'to put the equation into the slope-intercept form
\n" );
document.write( "4y = -5x + 20
\n" );
document.write( "y = (-5/4)x + 5
\n" );
document.write( "slope = (-5/4) and the y intercept is 5.  Pt (0,5) a point on the line.
\n" );
document.write( "(0,5)  The slope tells us the change in y versus the change in x
\n" );
document.write( "(4,0) also a point of the line (As y decreases by five,x increases by 4)
\n" );
document.write( "
