# Graphs

## x and y axis

The x axis is the horizontal axis and the y axis is the vertical axis.

Would you feel safer balancing the egg on the x or the y? We think you would prefer balancing the egg on X's horizontal expanse.

And

X is a cross, so the x axis is across.

x is a cross, so the x axis is across. Therefore, the y axis is vertical.

Example 1

All graphs have an x axis and a y axis.

Example 2

Both the x axis and y axis of a graph may also show negative values, as in the one above.
