Big Ideas:
The solution of a system of linear equations with two variables is a point that satisfies BOTH equations. That solution satisfies both conditions of a system.
This task builds on students' knowledge of solving linear equations. In this task, they are being exposed to utilizing two sets of information to define two unknown values. They will recognize that these values must satisfy both conditions. This will act as a foundational understanding for solving linear systems with two variables algebraically and by graphing.
Vocabulary: satisfies, conditions
