In two-dimensional Cartesian coordinate systems, what unit is used for the vertical axis?

Question

Quizplus · Accepted Answer

In a two-dimensional Cartesian coordinate system, the vertical axis is commonly represented by the unit y. The horizontal axis is commonly represented by the unit x. Therefore, Choice B is the correct answer. Choice A (x) is incorrect because x represents the horizontal axis, not the vertical axis. Choice C (z) is incorrect because z represents the depth axis in three-dimensional Cartesian coordinate systems, not the vertical axis. Choice D is incorrect because not all units can describe the vertical axis in a two-dimensional Cartesian coordinate system.
