I've just been playing around on Wolfram Alpha and I'm a bit puzzled with what Wolfram Alpha throws up for inequality plots.
Say I want to plot x greater than 4, well conventionally you would draw the line x = 4 and then shade to the right of it. Wolfram Alpha however returns this:

which plots the graph of y = x and the graph of y = 4 and then shades in the bit between when y = x is greater than y = 4. Both these approaches seem to make sense, but give different results! Why is Wolfram Alpha giving this (non usual) version rather than the other one?
Things look even more odd with other inequality plots:

This should give y greater than x + 4 but seems to give something else completely. What's going on?!
Thanks!
