AlgebraEasyPoint on a horizontal line
Algebra practice question
In the xy-plane, the graph of y = 2 is a horizontal line. Which of the following points lies on this line?
- A. (5, 2)Correct
- B. (2, 5)
- C. (2, 0)
- D. (0, 0)
Answer: A. (5, 2)
Every point on y = 2 has y-coordinate 2, whatever its x-coordinate: (5, 2).
Why the other answers are wrong
- B. (2, 5)
- (2, 5) has y = 5.
- C. (2, 0)
- (2, 0) has y = 0.
- D. (0, 0)
- (0, 0) has y = 0.
