You can put this solution on YOUR website!
Graph:
x + y < 4
Solve for "y";
y < -x + 4
Graph the boundary line, y = -x+4, as a dashed line
Then shade the half-plane BELOW the boundary as
you want y to be LESS than -x+4.

===============================================
x - y > 4
Solve for "y":
y < x -4
Boundary line y = x-4 as a dashed line.
Shade BELOW.
graph%28400%2C400%2C-10%2C10%2C-10%2C10%2Cy+%3C+x-4%29
