  2. 2. Variables and Patterns Definition: An amount that can change; Letters are used as symbols to represent variables. Variable Example: Your age, your height, your grade in math class!
  3. 3. Variables and Patterns Definition: A display of the relationship between 2 variables. Example: The relationship between time and distance. Coordinate Graph
  4. 4. Variables and Patterns Definition: The value of this variable is determined by the other variable. It is graphed on the Y- axis. Example: The cost of a long distance call depends on how long you talk. Dependent Variable
  5. 5. Variables and Patterns Definition : The number line that is vertical in a coordinate grid. Y axis X axis Y axis Example: How many students ate lunch on those days would go on the Y axis.
  6. 6. Variables and Patterns Definition: The value of this variable determines the value of the other variable. It is graphed on the X- axis. Independent Variable Example: Time is an independent variable.
  7. 7. Variables and Patterns Definition: The number line that is horizontal in a coordinate grid. X axis X axis Y axis Example: Days of the week would go on the X axis
  8. 8. Variables and Patterns Definition: A labeling plan used in the axes of a coordinate grid; Needs to be consistent and appropriate. Scale Example: On a map, 1 inch = 1 mile.
  9. 9. Variables and Patterns Definition: An ordered pair of numbers used to locate a point on a coordinate grid. Example: (X,Y) or (5,3) Coordinate Pair
  10. 10. Variables and Patterns Definition: An association between 2 or more variables. If one variable changes the other may change as well. Relationship Example: There is a relationship between gas in a car and how far driven.

  13. 13. Variables and Patterns Definition: To become different. Example: Temperatures rise and fall Prices will increase or decrease. Change
  14. 14. Variables and Patterns Definition: A rule with variables that represents a mathematical relationship. equation or formula Example: Area of a Circle has the formula A= r ²
  15. 15. Variables and Patterns Definition: A change that happens in an expected way. Pattern Example: 3, 6, 9, 12… forms a pattern of counting by 3’s
  16. 16. Variables and Patterns Definition: A predictable relationship that tells how to find the value of a variable. Rule Example: Distance is equal to rate X time; d=rt
  17. 17. Variables and Patterns Definition: A list of values for two or more variables showing a relationship. Table Example: Data from observations, experiments, or calculations. shirts cost 1 12.00 2 24.00 3 36.00 4 48.00 5 60.00
  18. 18. Variables and Patterns Definition: 1 st number in a coordinate pair. Example: (X,Y) or (5,3) X - Coordinate
  19. 19. Variables and Patterns Definition: 2 nd number in a coordinate pair. Example: (X,Y) or (5,3) Y - Coordinate
  20. 20. Variables and Patterns Definition: Amount of money a business takes in from selling products or charging fees Income Example: A theater takes in 5.00 for every person that comes to watch a movie.
  21. 21. Variables and Patterns Definition: Amount of money a business spends to run its activities. Cost Example: A theater spends 500.00 dollars a month for rent on the building.
  22. 22. Variables and Patterns Definition: Income minus cost; Income should be larger than the cost. Profit Example: A theater makes $1500.00 and pays $500.00 dollars a month for rent. The profit is $1000.00
