For # 13 which one is right and why

1 Answer

  • A.) y=3x-2 is the correct answer.
    The y in the equation simply refers to the y-values in the table.
    The x in the equation refers to the x-values in the table.
    Plug in each answer like so:
    y=3(-2)-2 -->  -6-2. Here you do a thing called KFC.
    Keep
    Flip
    Change
    You Keep -6
    You Change the minus sign in front of the 2 to make it a plus sign
    And then you change the positive 2 that is left into a negative 2.
    -6+(-2)=-8
    If you plug in each of the x-values, you then get the corresponding y-value making option A.) correct.
