Maximise the function
P =
x + 4 y
subject to the following constraints:
4 x + 2 y
≥
24
x + 3 y
≤
30

x, y ≥ 0
Enter two points for each constraint line to generate a plot in the window below.
You will see "yes" if your point lies on the constraint line and "no" if not.
A "yes" does not imply the point is a "good" one! Make the region clear to see!
