Question 116442
I Need help with understanding the Bondary line of a graph. 
Like for this problem -x+4y<-4. 
Also, when you have a fraction like 2/3 you go up 2, but how do you know to go left or right? 
-------------------
Solve for "y":
4y < x-4
y < (1/4)x-1
---------------------
Graph y = (1/4)x -1 as a dashed line
The half-plane solution set is below te line
because you want y to LESS THAN the boundary 
y-values.
---------------
I don't know what you mean by your question.
