Question

Which of the following points will lie on y-axis?

• A. (-4,0)
• B. (0,4)
• C. (4,0)
• D. (0,-4)

Answer 1

Answer: (B), (D)

The correct options are
B (0,4)
D (0,-4)

The Abscissa(x-coordinates) which are at zero distance from the y-axis lies on the y-axis.
ordinates(y-coordinates) which are at zero distance from the x-axis lies on the x-axis.

Points (0,4) and (0,-4) are at zero distance from the y-axis so these points will lie on the y-axis.
Whereas, (-4,0) and (4,0) are at zero distance from the x-axis and hence, they will on the x-axis.
