\r\n" );
document.write( "The given line has the slope of 2.\r\n" );
document.write( "\r\n" );
document.write( "Since the projected/requested line is parallel to the given line, it also has the slope of 2.\r\n" );
document.write( "\r\n" );
document.write( "Hence, the projected/requested line has an equation of the form  y = 2x + b  with unknown coefficient \"b\".\r\n" );
document.write( "\r\n" );
document.write( "To find \"b\", simply substitute the coordinates of the given point p and q as x and y respectively into this equation  y = 2x + b.  \r\n" );
document.write( "\r\n" );
document.write( "You will get\r\n" );
document.write( "\r\n" );
document.write( "    -1 = 2*5 + b,\r\n" );
document.write( "\r\n" );
document.write( "which implies  b = -1 - 2*5 = -1 - 10 = -11.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus your final equation of the projected/requested straight line in slope-intercept form is \r\n" );
