You can put this solution on YOUR website!
Graph the inequality.
4x + 5y <_ 20 (of course the _ goes under the <)
---------------------
1st: Graph the EQUALITY which is the boudary of the INEQUALITY.
y = (-4/5)x + 4

2nd: Shade the half-plane BELOW the line because your inequality
is LESS THAN.
========
The line and the shaded area comprise the graph of your problem.
