Systems with Parallel Lines
Solve Systems with Parallel Lines in Grade 9 algebra using graphing, substitution, and elimination. Classify systems as consistent, inconsistent, or dependent.
Key Concepts
Property Parallel boundary lines can result in no solution, a solution between the lines, or one solution being a subset of another. Explanation Parallel lines can be tricky! If their shaded areas point away from each other, there is no overlap and thus no solution. If they point toward each other, the solution is the strip of land between them. Examples $y \ge x+3$ and $y \le x 1$ have no solution as the shaded regions never intersect.
