Diketahui h(x)=ax+b. Jika h(4)=12 dan h(2)=10. Tentukanlah nilai h(1) Tolong Bantu dijawab..

Kelas 8 Matematika
Bab Fungsi

h(4) = 4a + b = 12
h(2) = 2a + b = 10
...........------------------ -
........... 2a = 2
........... a = 1

2a + b = 10
2 . 1 + b = 10
b = 10 - 2
b = 8

h(x) = x + 8

h(1) = 1 + 8
h(1) = 9
