Question

Which ordered pairs do not belong to a linear function in the form below?

Answer 1

Answer:

  B.  (0, 1); (1, 2); (2,5)

Step-by-step explanation:

All of the given answer choices have x-values that are sequential. A linear function will have y-values that are also evenly spaced.

  A: 0-1 = -1, -1-0 = -1 . . . . differences are the same

  B: 2-1 = 1, 5-2 - 3 . . .  . . differences are not the same, not a linear function

  C: 2-5 = -3, -1-2 = -3 . . . . differences are the same

  D: 1-1 = 0, 1-1 = 0 . . . . differences are the same
