On a standard Cartesian graph, there are two axes. The Y axis runs vertically, bottom to top and the X axis runs horizontally from left to right.
The 'Y' axis.
typically the y-axis. sometimes it changes when it fits the graph better, but always put the y-axis as the vertical one unless told to otherwise. when you get to 3-D drawins the y-axis is usually the vertical one but sometimes it changes.

The X axis.
On a standard Cartesian graph, there are two axes. The Y axis runs vertically, bottom to top and the X axis runs horizontally from left to right.
It is OFTEN the x axis, but not always. Sometimes it is the t-axis (for time). In basic economics it could be quantity (q), in demographics it could be age (y, for years). There are many alternatives.
The "Y" axis.
The 'Y' axis.
The y axis always runs vertically.
X Axis
Generally the x-axis is displayed on a 2-dimensional Cartesian Coordinate system running horizontally (left to right - for negative to positive values of x) In a 3-D graph, the x-axis is usually shown running diagonally from upper right to lower left (for negative to positive values of x) . In a 3-D graph, the y-axis is the one running horizontally and the z-axis is vertical.
