Algebra practice question
In the xy-plane, which of the following points is NOT on the graph of 4x + 3y = 24?
- A. (2, 5)Correct
- B. (0, 8)
- C. (6, 0)
- D. (3, 4)
Answer: A. (2, 5)
4(2) + 3(5) = 23, not 24. The other three points all satisfy the equation.
Why the other answers are wrong
- B. (0, 8)
- 4(0) + 3(8) = 24 ✓
- C. (6, 0)
- 4(6) + 3(0) = 24 ✓
- D. (3, 4)
- 4(3) + 3(4) = 24 ✓
