How do you graph the system #x>5# and #y<=4#?

See the explanation.


#x > 5# looks like this:

graph{x > 5 [-4.585, 17.915, -4.465, 6.785]}

#y <=4 # look like this:

graph{y <=4 [-5.99, 19.32, -5.17, 7.49]}

The conjunction ("and") requires both to be true, so we need the part of the plane where these overlap. That is: we need the part that is shaded on both graphs:

(I had to use a different graphing utility, so the colors are different and you cannot scroll this graph.)
