5x + b = 16 4x + b = 11 dikurangi nanti jadinya x = 5 5x + b = 16 5.5 + b = 16 b = 16 - 25 b = -9 h(-1) = ax + b = 5.(-1) + -9 = -5 + (-9) = -14 kayakya gitu

H(x) = ax + b

h(5) = 5x + b = 16
h(4) = 4x + b = 11 _
                 x = 7

h(5) = 5.7 + b = 16
           35 + b = 16
                  b = 16 - 35
                   b = -19

Jadi h(-1) = 7x - 19
       h(-1) = 7.-1 - 19
       h(-1) = -7 - 19
       h(-1) = -26


Ehh salah
Itu X-nya = 5
yang bener tu gimana seh
