It's not clear exaclty what you are looking for. For every situation that you are looking at, will there be a point at the origin, and will there be a point on the x-axis and y-axis? Or are you just looking for the intersection point between the black and red lines?

You probably want to use the code plotregion, by Per Bergström. It can be found on the file exchange.
Of course, if you have a 4-d problem or greater, then nothing will work, at least to plot.
plotregion handles general sets of linear inequality constraints, as well as bound constraints. If you have equality constraints too, things will become more complex.
If your goal is to find the intersection points themselves, then a tool like this may be appropriate, thus the function LCON2VERT from this set of tools by Matt J.
As well, there are tools from Michael Kleder, which apparently inspired the tools from Matt.
