pertidaksamaan
3x + 6y ≤ 12
kedua ruas bagi (3)
x + 2y ≤ 4
x + 2y = 4
• titik potong dg sumbu x → y = 0
x + 2.0 = 4
x = 4
tipot A(4,0)
• titik potong dg sumbu y → x = 0
0 + 2y = 4
y = 2
tipot B(0,2)
buat garis melalui A dan B
arah arsiran → uji titik (0,0)
x + 2y … 4
0 + 2.0 … 4
0 < 4 memenuhi
arah arsiran memuat titik (0,0)
