SAT Math Multiple Choice Question 693: Answer and Explanation
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.
