Linear Regression Intercept

The Linear Regression Intercept Line is not showing on Chart. Please HELP.

x = Cum(1);
lastx = LastValue( x ); Daysback = 14; 
aa = LastValue(LinRegIntercept( Close, Daysback) );
bb = LastValue( LinRegSlope( Close, Daysback ) );
y = Aa + bb * ( x - (Lastx - DaysBack) );
 Plot( Close, "Close",colorWhite, styleCandle );
Plot( IIf( x >= (lastx - Daysback), y, -1e10 ), "LinReg", colorRed);

@drana, the code plots, but what are you expecting?

You are getting the LR line plotted, and the LR Intercept is just a value used in the calculations, so why are you expecting a Line from it as well?
