  1. well, just plug in the x value and see whether you get the y value.

    For example, when x=0,

    2*0 - 3 = -3 Nope, You want 3.

    Now try the others. One will work.

  2. Still Don't Get It Minion? Lets Work It Out:

    A. (-2, 7)
    2 * -2 = -4
    -4 - 3 = -7
    So, This Wouldn't Be Right Because You're Looking For 7, not -7.

    B. (0, 3)
    2 * 0 - 3 = -3
    So, This Wouldn't Be Right Because Your're Looking For 3, not -3

    C. (-4, -11)
    2 * -4 = -8
    -8 - 3 = -11
    So, This IS Right Because The Final Result Matches The Result to This Answer Choice.

    D. (5, -7)
    2 * 5 = 10
    10 - 3 = 7
    So, This Wouldn't Be Right Because You're Looking For -7, Not 7.

    So, The Correct Answer To This Question Is: C. (-4, -11)


    Have A Nice Day!
