Question 349098
How do I graph 2y-5x<13
------
Note: You NEVER graph an inequality directly.
You graph the boundary, which is an equality.
-----------
1st: Solve for "y"
2y < 5x+13
y < (5/2)x + (13/2)
----------------
2nd: Graph y = (5/2)x+(13/2)
as a dashed line.  That is the boundary.
-----
3rd: Shade the halp-plane BELOW the boundary
because you want y to be LESS than (5/2)x+(13/2).
---
That is the graph of the inequality.
-----------
{{{graph(400,300,-10,10,-10,10,y<(5/2)x+(13/2))}}}
----------------
