This graph shows a pattern.

Is the pattern additive or multiplicative?

additive

multiplicative

Write a rule for the pattern.

To determine the rule for the pattern, you can make an input/output table.

Start by finding the input and output values for the first point.

The first input/output pair is

(

)

You can find the input/output pairs for the other points the same way. This table shows all of the pairs from the graph.

Find how the inputs and outputs are related to determine the rule.

In words, the rule is:

To get each output, you add 6 to the input.

Because you add 6, the pattern is

additive.

As an equation, the rule is:

$Confetti$
