Kelas 11 MatematikaBab Program Linear
(4,0) dan (0,6)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 0)/(6 - 0) = (x - 4)/(0 - 4)
-4y = 6 (x - 4)
-4y = 6x - 24
6x + 4y = 24
3x + 2y = 12
karena menuju titik (0,0), maka 3x + 2y ≤ 12
(8, 0) dan (0,4)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 0)/(4 - 0) = (x - 8)/(0 - 8)
-8y = 4 (x - 8)
-2y = x - 8
x + 2y = 8
karena menuju titik (0,0), maka x + 2y ≤ 8
Daerah yang diraster adalah
3x + 2y ≤ 12; x + 2y ≤ 8; x ≥ 0; y ≥ 0
