Definition of the solution of an equation in two variables If a true statement results when the numbers in an ordered pair are substituted into an equation in two variables, then the ordered pair is a solution of the equation
More Since the solutions of an equation in two variables are ordered pairs, such an equation describes a relation. The set of values of x is the domain of the relation. The set of corresponding values of y is the range of the relation.
Homework problems #4,5 are table of values to complete #6-8/13-15 are multiple choice. #9-12/16-23 are solve for the variable indicated #24-41 are given that domain is, then solve each equation for the range. You need a ruler to make tables or be careful making them.
