					   Relations are common in everyday life:
    ◦ When you drive a car, the distance you travel is
      related to how fast and how long you drive
    ◦ The amount of an iceberg above the water is related
      to the amount below the surface
   When we are looking at relations, we will be
    talking about sets of numbers
    ◦ One set is called an ordered pair
   The ordered pair contains specific
    information
    ◦ Domain ( the set of first coordinates in the ordered
      pair)
    ◦ Range (the second coordinate in the ordered pair)
   There are 4 different ways of showing
    relations:
    ◦   Graphically
    ◦   Chart form/table of values
    ◦   Mapping Diagrams
    ◦   Equations
