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!

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))
