In a coordinate plane, what is the name of the vertical axis?

Explanation:
In a coordinate plane, the vertical axis carries the y-values, so it is the Y-axis. The horizontal axis carries the x-values, and they intersect at the origin, (0, 0). The term “Domain” refers to the set of possible x-values for a function, not an axis name. For a point like (3, -2), 3 is how far along the horizontal axis you move, and -2 is how far along the vertical axis you move. This is why the vertical axis is the Y-axis.
