F(x) = px - q
f(1) = p - q = -2
f(2) = 2p - q = 2
Eliminasi q diperoleh:
p - q = -2
2p - q = 2
------------- -
-p = -4 maka p = 4
substitusikan p = 4.
p - q = -2
4 - q = -2
q = 6
fungsi tersebut f(x) = 4x - 6

P - q = -2
2p - q = 2
~~eliminasi~~
-p = -4
p = 4

p - q = -2
4 - q = -2
q =  6

f (x)  = px - q
f (x) = 4x - 6
