diketahui G(x)=ax+b.jika G(-2)=-4 dan G(-6)=12,maka bentuk fungsi G adalah...

Matematika SMP Kelas VIII

G(-2) = -2a + b = -4
G(-6) = -6a + b = 12
..............------------------ -
........................ 4a = -16
.......................... a = -4

-2a + b = -4
-2 . (-4) + b = -4
b = -8 - 4
b = -12

G (x) = -4x - 12
