How to get mupad to plot solution points for inequalities?

I am new to MuPAD and have just figured out how to graph inequalities using, for example:

plot(plot::Inequality([-x+y>=-2,x<=4],
                      x = -10..10, y = -10..10))

How do I get it to plot or print the solution/intersection points, i.e. (4,2) on the same graph or in the command line?

Am using MATLAB 2013a.

Thanks!

I don't think you can type it in the command line. the way I would do it is type >> mupad in the command window, and then!!! type

"plot(plot::Inequality([fill in]))" in the mupad window

The intersection of your boundaries will be on the boundaries (I know, not surprising), so you can simply say solve([-x+y = -2, x = 4]). If you want to include them in the plot, try something like this:

S := solve([-x+y = -2, x=4], [x, y], VectorFormat):

plot(plot::Inequality([-x+y >= -2, x <= 4],
                      x = -10..10, y = -10..10),
     map(S, plot::Point2d, PointSize = 2, Color = RGB::Blue))

Better late than never! Thank you for your answer. Unfortunately I get the message - "Error: An equation is expected. [rhs]" when trying to plot.
