Hi. It is one of the three axis names used in the Cartesian coordinate system. Usually it lies in the same plane as the x axis and is perpendicular to it. If you image these two axes on a sheet of paper then the third, called the z axis, goes in and out of the paper.

Another important thing about the y axis is that for most math equations you'll need to graph, the y axis is "output."
Take something simple, like y=x+2. Say you put in x=1. That gives you the output, y=3.
To graph it, you'd start at the mark for 1 on the x axis, then count upward on the graph paper until you hit 3 on the y axis. The dot you make will be 1 to the right and 3 high.

It's the vertical line on a graph. AKA, the one that goes up and down.
