Need a clear visual for graphing linear inequalities on the coordinate plane? This Grade 8 / Algebra 1 anchor chart shows students exactly when to use a dashed or solid boundary line, where to shade, and how to interpret the solution region — making half-planes easier to teach, easier to see, and easier to remember. Details included Boundary Line Type tiles (black line only): dashed = not included, solid = included Shading Rule tiles: below/left for <, ≤ and above/right for >, ≥ (vertical
