Question 986118
The graph is below but there are two things missing:
1.  The line should be dotted, for it is an inequality.
2.  There is no shading put in.  The way to deal with that is to pick the origin, where x and y are both zero.  0<4, so the part of the graph that contains the origin should be shaded,  Everything below the line should be shaded.

{{{graph(300,200,-10,10,-10,10,-x+4)}}}
