The x-axis and y-axis Remembered! The x-axis and y-axis are two lines that create the coordinate plane. The x-axis is a horizontal line and the y-axis is a vertical line. I'm sure you've heard that a million times, but it might hard for you to remember which one is which. Here is a little trick to help you remember...
the x and y is the name of the axis, you need to label the axis on a graph as X and Y. X is the the line that goes horizontally and y is the one that goes in a portrait way.â¦ the way to remember is . if you cross your hand to make the X letter one hand goes across the other therefore the axis x is the line that is going across.
