diketahui persamaan garis 2y 3x 6 lengkapilah tabel berikut
Diketahui persamaan garis 2y = 3x – 6
daerah asal (x) = {-4 , -2 , 0 , 2 , 4 , 6}
Pembahasan :
menetukan daerah hasil
2y = 3x – 6
x = -4 → 2y = 3(-4) – 6
2y = -12 – 6
2y = -18
y = -18 / 2
y = -9
x = -2 → 2y = 3(-2) – 6
2y = -6 – 6
2y = -12
y = -12 / 2
y = -6
x = 0 → 2y = 3(0) – 6
2y = -6
y = -6 / 2
y = -3
x = 2 → 2y = 3(2) – 6
2y = 6 – 6
2y = 0
y = 0/2
y = 0
x = 4 → 2y = 3(4) – 6
2y = 12 – 6
2y = 6
y = 6 / 2
y = 3
x = 6 → 2y = 3(6) – 6
2y = 18 – 6
2y = 12
y = 12 / 2
y = 6
HPB = {(-4 , -9) , (-2 , -6) , (0 , -3) , (2 , 0) , (4 , 3) , (6 , 6)}
