document.write( "find two points on each line, plot them and connect with corresponding line
\n" );
document.write( "y = 2x     x = 0 ⇒ y = 0     x = 1 ⇒ y = 2  
\n" );
document.write( "y = -2x + 8  x = 0 ⇒ y = 8     x = 1 ⇒ y = 6  
\n" );
document.write( "Lines intersect at P(2,4) which is the solution  for this system of Equations
\n" );
document.write( "Note: 2x = -2x + 8,  4x = 8 , x = 2 (substituting for x in either EQ ⇒ y = 4)
