# x, y, z coordinates

In this chapter we’re going to be looking at coordinates. The x, y, and z coordinates on a graph. The graph below shows the x and y coordinates.
Any graph has four different regions where x and y-coordinates are either positive or negative. These regions are shown below.
When noting down the coordinates on a graph you have to always remember that the coordinates are written in alphabetical order. The x-coordinate comes first then the y-coordinate.
You also have to remember that the x-coordinate is along the x-axis which is the horizontal line across the graph. The y-coordinate is the axis which is the vertical line in the graph.
