Question

the x axis is the ______ line that passes through the origin.

Explanation:

In the Cartesian coordinate system, the x - axis is defined as the horizontal line that passes through the origin (where the x - coordinate and y - coordinate are both 0).

The key characteristic of the x - axis is its horizontal orientation relative to the y - axis (the vertical line through the origin).

Answer:

horizontal
