### It is also important to include a title to specifically describe what the data pertains to.

• Draw a graph of an event, and describe the event with words (write a story).

• Include labels, units, and a title with your graph.

• In nature, there are only a few basic graph shapes that describe many phenomenon such as gravity, light intensities, growth and decay rates, etc.

• In this class, we will focus on four of these shapes of graphs.

• In science, the objective of a graph is often to describe the relationship between the independent and dependent variables.

• The relation between variables can be stated as an equation… The equation of the graphed line.

The simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.Linear Graph

The Graph of a simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.SquareOr graph of the independent variable raised to a power.

The Graph of a simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.Square Root

The Graph of an simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.Inverse relationOr graph of the independent x-axis raised to the -1 power.

Determine the relation which the given data describes. simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.
