==================================================================================== Required Prior Knowledge
Students should know:
♦ A system of equations can have one solution, no solution, or infinitely many solutions
♦ How to solve systems of equations by substitution and elimination
Common Core Standards 8.EE.C.8
Analyze and solve pairs of simultaneous linear equations. 8.EE.C.8a
Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously. 8.EE.C.8.b
Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. HSA.REI.C.6
Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
