Question 292778
Show me how to graph this inequality equation x+y<3
-----
You don't graph inequalities directly.
You graph the boundary, which is always an equality.
-----------------------
Rearrange:
y < -x + 3
-----
Graph the boundary line y = -x+3 as a dashed line.
{{{graph(400,300,-10,10,-10,10,-x+3)}}}
------
Select at test point, such as (0,0) and test it 
in the inequality:
0 < 0+3
That is correct and means (0,0) is in the solution set
of the inequality.
----
Shade the area below the boundary line which does include (0,0)
--
That shaded area is the graph of your inequality.
