Algebra practice question
A table lists values of y = 3x + 1. Which of the following rows is correct?
- A. x = 2, y = 7Correct
- B. x = 2, y = 6
- C. x = 2, y = 5
- D. x = 2, y = 9
Answer: A. x = 2, y = 7
3(2) + 1 = 7.
Why the other answers are wrong
- B. x = 2, y = 6
- 6 is 3(2) without the +1.
- C. x = 2, y = 5
- 5 is 2 + 3, adding instead of multiplying.
- D. x = 2, y = 9
- 9 is 3(2 + 1).
