    Answer: option c: y = 3x

    Justification:

    All the ordered pairs meet that the second number of the pair equal 3 times the first number of the pair:

    Here is the proof:

    Pair first number times 3 second number of the pair

    (1, 3) 3 * 1 = 3 3 = > check

    (2,6) 2 * 3 = 6 6 = > check

    (3,9) 3 * 3 = 9 9 = > check

    (4,12) 3 * 4 = 12 12 = > check

    (5, 15) 3 * 5 = 15 15 = > check.

    So, all the pairs meet the rule y = 3x
