Grade 9 systems include two linear equations and, later, a linear inequality pair whose solution is a region. Students choose graphing, substitution, or elimination, and they write systems from mix, ticket, or distance contexts. A point is a solution of an inequality system only if it satisfies every inequality.

What you practice

These are the Grade 9 Systems of Equations & Inequalities skills this quiz is built around.

Solve a 2×2 linear system by substitution or elimination and check both equations.
Classify a system as one solution, none, or infinitely many from slopes and intercepts.
Graph a system of linear inequalities and test a point in the overlapping region.

A useful tip

Substitution is efficient when a variable is already isolated. Elimination is efficient when coefficients are opposites or easy to match by multiplication.
