F(x) = ax + b f(1) = a(1) + b = 3 => a + b = 3 f(8) = a(8) + b = 10 => 8a + b = 10 Eliminasi pers 1 ke pers 2 tuk mncri nilai b a + b = 3 |x8 | 8a + 8b = 24 8a + b = 10 |x1| 8a + b = 10 -- 7b = 14 b = 14/7 = 2 tuk nilai a, subs nilai b ke pers. 1 atau pun 2 & hasilnya => a + b = 3 a + 2 = 3 a = 3 - 2 a = 1 jdi f(x) = ax + b f(10) = 1(10) + 2 f(10) = 12

f(1) = a(1) + b = 3 => a + b = 3
f(8) = a(8) + b = 10 => 8a + b = 10
Eliminasi pers 1 ke pers 2 tuk mncri nilai b
a + b = 3 |x8 | 8a + 8b = 24
8a + b = 10 |x1| 8a + b = 10 --
7b = 14
b = 14/7 = 2
tuk nilai a, subs nilai b ke pers. 1 atau pun 2
& hasilnya => a + b = 3
a + 2 = 3
a = 3 - 2
a = 1
jdi f(x) = ax + b
f(10) = 1(10) + 2
f(10) = 12
