document.write( "Using the point-slope formula, to determine slope of L1
\n" );
document.write( "Points are (-4,0) and (0,6)which are the x and y intercepts 
\n" );
document.write( "  m = 6-0  / 0-(-4) = 6/4 = 3/2  
\n" );
document.write( "the standard slope-intercept form for an equation of a line is: y = mx + b  
\n" );
document.write( "where m is the slope and b the y-intercept.  Equation of L1 is y = (3/2)x + 6
\n" );
document.write( "Line2 parellel to L1 also has slope of 3/2
\n" );
document.write( " y = 3/2x + b   L2 is to pass thru Pt(0,0) so b = 0
\n" );
document.write( "Equation of L2 is y = (3/2)x
