    F(x) = ax +b
    F(2) = a.2+b = 1 l 2x l 4a + 2b = 2
    F(4) = a.4+b = 5 l 1 x l 4a + b = 5 _
    b = -3
    2a + b = 1
    2a + -3 = 1
    2a = 1 +3
    2a = 4
    a = 4/2 = 2

    F(10) = a.10 + b
    2x10 + (-3)
    18

    No 2.
    F(x) = -2x + 5
    F(-2) = -2.(-2) + 5 = 1

    No 3.
    F(x) = ax + b
    F(-1) = a.-1 + b = -2
    F(6) = a.6 + b = 33 _
    7a = 35
    a = 35/7 = 5
    a.-1 + b = -2
    5.-1 + b = -2
    b = -2 + 5 = 3

    Semoga membantu
