This topic introduces students to systems of linear equations by comparing distance-time graphs to determine
which of two objects has greater speed (8.EE.B.5, 8.EE.C.8c).
In the Opening Exercise students complete Exercises 1–3 as an introduction to simultaneous linear equations in a familiar context. Example 1 demonstrates what happens to the graph of a line when th...
In this lesson, students graph two linear equations on a coordinate plane and identify the point of intersection of the two lines as the solution to the system (8.EE.C.8a). Next, students look at s...
This lesson continues the thinking that a system can have no solutions because parallel lines do not have a point of intersection with respect to systems that have infinitely many solutions (8.EE.C...
