Question 144432
2x+3y<=6 
3y<=6-2x
y<=2-(2/3)x

Plot that function as normal (y intercept=2; the graph goes DOWN 2 and TO THE RIGHT 3 for each whole number plot point because of the slope). Now, where is the function valued less than or equal to that line? Just shade below the line.

{{{graph( 300, 200, -5, 5, -5, 5, 2-(2/3)x )}}}
