I have two points (0,0) and (5,-5). How can I plot the stability phase diagram for these two points in a single StreamPlot in Mathematica by showing those points with dots?

- $\begingroup$ Are these points fix points? If so, a stream plot of the linearized equations about those points will show you if the you have a sink, a source, a saddle, spiral source/sink,... $\endgroup$Daniel Huber– Daniel Huber2021-03-24 17:15:42 +00:00Commented Mar 24, 2021 at 17:15

1 Without your function we can't give a full answer, but this should suffice:
StreamPlot[{-1 - x^2 + y, 1 + x - y^2}, {x, -6, 6}, {y, -6, 6}, Epilog -> {Red, PointSize[0.03], Point[{0, 0}], Point[{-5, 5}]}]
