Introduction to Graphing and Equations in Two Variables
This activity introduces equations in two variables. Data values are presented in xy-tables, and graphs -- both linear and nonlinear -- are used to introduce students to the coordinate plane, ordered pairs, and graphs. Characteristics and vocabulary such as intercepts, origin, and quadrants are introduced. In addition, the activity covers how to determine if an ordered pair is a solution to a two-variable equation, finding the intercepts of a two-variable equation, and using the intercepts to graph a linear equation.
