comment Finding a point above the line in $O(\log n)$
Henning Makholm, Thank you very much for the answer, how it can be extended to the segment instead of line. Let's say now instead of line $l$ we have a segment, of course x coordinates of point must lie between x coordinates of the endpoints of e.
