document.write( "\r\n" );
document.write( "ANSWER.  y = 7x - 20.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Explanation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "x = 2, 3, 4, . . . , 8  are consecutive integer numbers from 2 to 8 inclusive.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "y increases by 7 every time as x increases by 1.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So you write  y = 7x + c     (1)    (linear function with the slope of 7).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The constant \"c\" is unknown now.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To find it, you substitute x = 2 to the right side of (1), and substitute y= -14 to the left side of (1).\r\n" );
document.write( "\r\n" );
document.write( "In this way, you get  c = -20.\r\n" );
