You can put this solution on YOUR website!
4x+5y<=20
5y<=-4x+20
/5
y<=-4x/5 +4
x=0,y=4 (0,4)
y=0,x=5 (5,0)
For defining the boundary find the y& x intercept points. Join them and draw the line. Since y is < than someting all points below the line are solutions to the inequality.
The boundary

The inequality
