The question makes no sense.
There are an infinite number of points which are not part of the solution.
Here is what the graph looks like

Graph the inequality y < –|x – 4|. Which point is NOT part of the solution?

when x=4, y<-0 which is a questionable use of zero. IEEE standard in computing allows zero with signs as an aid to computing, but in ordinary computation, it has no meaning. y being less than something with no meaning is questionable.
