document.write( "To determine the coefficient \"c\", substitute y=4 and x=1 into this equation.\r\n" );
document.write( "\r\n" );
document.write( "You will get\r\n" );

document.write( "c = 7.\r\n" );
document.write( "\r\n" );
document.write( "Hence, y = -3x + 7 is the equation of your straight line.\r\n" );
