Unit 5

Systems of Linear Equations

Graphing, substitution, and elimination. Grade 8 introduces systems; Algebra I requires fluency and the f(x) = g(x) intersection view.

Both exams

Essential question: How can two conditions be true at the same time?

A solution to a system is an ordered pair that makes both equations true — the intersection of two lines, or the x where f(x) = g(x).
