You can put this solution on YOUR website! find: x plus 4<12.
----
x + 4 < 12
x < 8
------
You can graph that on a number line of on an x/y coordinate plane.
-----
Put an open circle on the number line and call it "8"
Draw an arrow from that point to the left; that is your 1-dimensional graph.
----
OR
Draw a dashed line thru points where x = 8
----------
Shade the half-plane to the left of that boundary line.
That is your 2-dimensional graph.
