\n" );
document.write( "Ordered pairs (x,y)
\n" );
document.write( "(3,18)
\n" );
document.write( "(1,8)  m = 10/2 = 5
\n" );
document.write( " y = mx + b
\n" );
document.write( " y = 5x + b
\n" );
document.write( " 8 = 5 + b     || using order pair (x,y): (1,8) to solve for b
\n" );
document.write( " 3 = b
\n" );
document.write( " y = 5x + 3 \n" );
