ÞA _____________________ is any set of ordered pairs that express a relationship.

ÞA _____________________ is a relationship between two variables. This is also defined as

_______________________.

ÞThe number being _____________________ or _______________________ is always the

_________________ when the _________________ is zero (0).

ÞThe number _______________________ or _____________________ determines the

pattern of the _____________________.

ÞThe __________________ (____) is put into the function rule to determine each

__________________ (____).

ÞThe _______________________________________ only works if there is one point on the

line. This test helps to determine functionality of an x, y relationship.
