What is the Y-Axis and X-Axis?

The Y-Axis is the vertical line on a graph, running from the bottom to the top. The X-Axis is the horizontal line on a graph, running from left to right. These two lines are used to create a coordinate system, which is used to plot data points on a graph.

The Y-Axis is usually labelled with the variable that is being measured, while the X-Axis is usually labelled with the units of measurement. For example, if you were graphing the height of people in your class, the Y-Axis would be labelled “Height (in inches),” while the X-Axis would be labelled “Person.”

When you plot data points on a graph, you need to specify both an X and Y value for each point. The X value tells you how far along the X-Axis the point is, while the Y value tells you how far along the Y-Axis it is. For example, if you were graphing someone’s height, their X value might be their age (measured in years), while their Y value would be their height (measured in inches).

You can use these coordinates to find out specific information about where each point lies in relation to other points on the graph. For example, if two people are both five feet tall but one person is ten years old and one person is twenty years old, you can tell that person A is taller than person B by looking at their respective coordinates: Person A’s coordinate would be (10, 60), while person B’s coordinate would be (20, 50). This also works for more than two points – if you have three people who are all five feet tall but one person is ten years old, one person is fifteen years old, and one person was twenty years old, you can tell that person C is taller than both A and B by looking at their coordinates: Person A’s coordinate would be (10 ,60), Person B’s coordinate would be (15 ,50), and Person C’s coordinate would 20 ,50).
