graph

A graph is a picture that shows how two or more things are related. For example, you could make a graph to show how the temperature changes over time, or how the height of a plant changes over time.

Graphs have two parts: the x-axis and the y-axis. The x-axis is usually the horizontal line, and the y-axis is usually the vertical line. The numbers on the x-axis tell you what the value of the first thing is, and the numbers on the y-axis tell you what the value of the second thing is.

The points on the graph show you how the two things are related. For example, if you were making a graph to show how the temperature changes over time, you would put the time on the x-axis and the temperature on the y-axis. Then, you would put a point on the graph for each time and temperature that you measured.

Graphs are a great way to show how things are related. They can be used to show trends, compare different things, or make predictions.

The graph shows the relationship between temperature and pressure.
