Standard(s): A.REI.C.6: Solve systems of linear equations exactly and approximately (e.g., with grap), focusing on pairs of linear equations in two variables.
Essential Question: How can I use Algebra to describe the relationship between sets of numbers? In what ways can the problem be solved, and why should one method be chosen over another?
Learning Target: I can write the system of equations that best models the problem.(Synthesis) I can interpret solutions in the context of the situation modeled and the scenario.(Evaluation) I can define systems of linear equations.(Knowledge) I can define solutions of systems of equations.(Knowledge) I can explain why some linear systems have no solutions.(Comprehension) I can identify linear systems with no solutions.(Comprehension) I can explain why some linear systems have infinite solutions.(Comprehension) I can identify linear systems with infinite solutions.(Comprehension) I can solve a system of linear equations algebraically to find an exact solution.(Application) I can explain that a point of intersection on the graph of a system of equations is the solution to both equations. (Comprehension) I can use function notation to show that when f(x)=y and g(x)=y that f(x)=g(x).(Application) I can explain that the value making f(x)=g(x) true is the x coordinate of the intersection point.(Comprehension)
