Graph the inequality on a plane
4x+5y<_ 20
----
1st: Graph the boundary line:
y = (-4/5)x+4
----
2nd: Graph the inequality:
y < (-4/5)x+4
Shade the half-plane BELOW the boundary.

4x%2B5y%3C=+20
add-4x
5y%3C=+-4x%2B20
divide by 5
y%3C=%28-4%2F5%29x%2B4
...
The boundary will be y=%28-4%2F5%29x%2B5
The Boundary
graph%28300%2C300%2C-6%2C6%2C-6%2C6%2Cy=%28-4x%2F5%29%2B5%29%29
The inequality graph%28300%2C300%2C-6%2C6%2C-6%2C6%2Cy%3C=%28-4x%2F5%29%2B5%29%29
