1.  A _____________________ is any set of ordered pairs that express a relationship.  A _____________________ is a relationship between two variables. This is also defined as _______________________.  The number being _____________________ or _______________________ is always the _________________ when the _________________ is zero (0).  The number _______________________ or _____________________ determines the pattern of the _____________________.  The __________________ (____) is put into the function rule to determine each __________________ (____).  The _______________________________________ only works if there is one point on the line. This test helps to determine functionality of an x, y relationship. RELATIONSUBTRACTED DIVIDED VERTICAL LINE TEST INPUTOUTPUTADDED FUNCTIONDIAGRAM MULTIPLIED ONE-TO-ONE GRAPH X OUTPUTINPUTYOUTPUT
