3. Images

Based on the ordered pairs in the table above, which of the following could express a relationship between x and y?

  • A. y = x + 4
  • B. y = 2x
  • C. y = 2x + 2
  • D. y = 2x + 4

Correct Answer: C



Algebra/Data Analysis (expressing relationships) EASY

The first ordered pair, x = 0 and y = 2, does not satisfy the equations in (A), (B), or (D), so those choices can be eliminated. You should also confirm that the equation in (C), y = 2x + 2, is satisfied by all four ordered pairs.
