Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

How do you identify a multiplicative pattern in a table?

Back

A multiplicative pattern occurs when each value in one column can be obtained by multiplying the corresponding value in another column by a constant factor.

Front

What is an additive pattern?

Back

An additive pattern occurs when a constant is added to each value in a sequence to get the next value.

Front

What does the equation y = x - 9 represent in a real-world context?

Back

This equation shows that the value of y is 9 less than the value of x, which can represent a comparison of lengths or quantities.

Front

How can you determine which graph matches a given table of values?

Back

To determine the correct graph, plot the ordered pairs from the table on a coordinate plane and see which graph passes through those points.

Front

What is the significance of the point (0,0) in a pattern?

Back

The point (0,0) is the origin in a coordinate plane and can indicate the starting point of a pattern or relationship.

Front

What does it mean for a pattern to be 'doubled'?

Back

A pattern is 'doubled' when each value is twice the value of the corresponding previous value.

Front

What is the difference between additive and multiplicative patterns?

Back

Additive patterns involve adding a constant to get the next term, while multiplicative patterns involve multiplying by a constant.

Front

How do you write an equation from a word problem?

Back

Identify the quantities involved, determine their relationships, and express them using variables and mathematical operations.

Front

What is a variable in mathematics?

Back

A variable is a symbol, often a letter, that represents an unknown value in an equation or expression.
