Question

1. which axis is the horizontal axis on a coordinate plane?

a. x - axis
b. z - axis
c. w - axis
d. y - axis

Explanation:

In a two - dimensional coordinate plane, the x - axis is the horizontal axis. The y - axis is the vertical axis. In three - dimensional space, there is also a z - axis, but it is not relevant to the two - dimensional horizontal axis question. There is no standard w - axis in common coordinate systems.

Answer:

A. x - axis
