# Q2 W3 Oct 28-Nov 1 Algebra 1 Teacher Stephanie Durrance Algebra I Honors 7th/8th 3 UNIT 5 – SYSTEMS OF LINEAR EQUATIONS AND INEQUALITIES
Standard(s) Taught
 MAFS.912.F-IF.3.7a: Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated functions. MAFS.912.A-REI.3.6: Solve systems of linear equations exactly and approximately (with graphs), focusing on pairs of linear equations in two variables.
Learning Targets and Learning Criteria

• explain why and identify when some linear systems have no solutions or infinitely many solutions. • identify systems whose solutions would be the same through examination of the coefficients. • solve a system of linear equations algebraically (by substitution or elimination) to find an exact solution. • graph a system of linear equations using appropriate axis labels and scale and determine the approximate solution by estimating the point of intersection. • explain the steps in an algebraic proof that shows one equation being replaced with another to find a solution for a system of equations. • explain why a method was chosen when solving a system of equation.
