Penjelasan dengan langkah-langkah:
f(x) = ax + b
Tekhnik substitusi :
(2, -2) ⇒ -2 = 2a + b
b = -2 - 2a
(-2, 6) ⇒ 6 = -2a + b
6 = -2a + (-2 - 2a)
6 = -2a - 2 - 2a
6 + 2 = -4a
8 = -4a
a = 8/(-4) = -2
b = -2 - 2(-2) = -2 + 4 = 2
F(x) = -2x + 2
Atau
Tekhnik Eliminasi :
2a + b = -2
-2a + b = 6
4a = -8
a = -8/4 = -2
2(-2) + b = -2
-4 + b = -2
b = -2 + 4 = 2
