Standard(s) Taught

#### Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection.

Learning Targets and Learning Criteria

Students are successful when they can…

• graph a system of linear equations
• identify the points of intersection as a solution to a system of linear equations.
• define the solution to a linear equations as the intersection point on a graph.
• identify the graph of 0, 1, infinitely many solutions for a system of equations.
