https://ask.sagemath.org/question/41544/place-a-point-on-a-graph/?answer=41551#post-id-41551There are a lot of different functions for plotting, not only `plot`. In your situation there is `point` (or `point2d`) and `text` (or `text2d`). Both of them are documented at http://doc.sagemath.org/html/en/reference/plotting/sage/plot/plot.htmlWed, 14 Mar 2018 22:13:06 +0100https://ask.sagemath.org/question/41544/place-a-point-on-a-graph/?answer=41551#post-id-41551
