F(x) = mx + n

f(1) = 1m + n = 5
f(-3) = -3m + n = -23
____________________-
        4m         = 28
         m          = 28/4
         m          = 7



f(1) = 1*7 + n = 5
     = 7 + n = 5
n = 5 - 7
n = -2


yang ditanya: f(5)

f(5) = 5*7 + (-2)
    = 35 - 2
    = 33

Raihan makasih banyak salam kenal yaa :D
ok, sama sama :)
