    I just tried working this one out and I can't find the answer. Maybe nothing further can be determined that I know so far.

    y = 3x - 1

    Step-by-step explanation:

    Given the data set: (1, 2) (2, 5) and (3, 8), you first need to look for a constant difference in the values of x and y:

    x: 1 2 3 (add '1' each time)

    y: 2 5 8 (add '3' each time)

    Rate of change (slope) can be found by dividing y/x:

    3/1 = 3

    Since y = 2 when x = 1, then y = - 1 when x = 0.

    Using slope-intercept formula: y mx + b

    y = 3x - 1
