What is the common term for the set of all points with x- coordinate zero?

A. X axis

B. Y axis

C. Coordinate plane

D. Origin

Answer 1

I think the correct answer would be option B. The common term for the set of all points with the x-coordinate that is zero is the y-axis. All of the points that is found in the y-axis contains zero as the x-coordinate of the point. So, it should be the y-axis the correct answer.
