f(1) = -2 1a+b = -2
f(4) = 1 4a+b = 1
__________________ _
-3a = -3
a = -3/-3 = 1 (Nilai A)
Mencari nilai b :
a =1 1a + b =-2
1(1)+b =-2
1 + b =-2
b = -2 -1 = -3
Fungsi = f(x) = 1x + -3
Sorry Kalo Acak'" an
f(1) ⇒ 1a+b = -2
f(4) ⇒ 4a+b = 1
persamaan garis
a+b = -2
4a+b = 1 _ eliminasikan
-3a = -3
a = -3/-3
a = 1
subtitusikan
a + b = -2
b = -2 - a
b = -2 - 1
b = -3
nilai a = 1
nilai b = -3
bentuk fungs
f(x) = ax + b
= x - 3
