The modeled example begins by identifying the y-intercept and slope of each line so the inequalities can be written in slope-intercept form. Students then examine the shaded solution area to determine whether each inequality represents values that are greater than or less than the boundary line. The lesson also emphasizes how to use the graph to decide whether the boundary is dashed or solid, helping students determine if the inequality symbol includes equality or not. By connecting graphical features to algebraic representations, this video builds students’ ability to translate between representations and justify their reasoning. The task reflects what all Algebra 1 students should know and be able to do in alignment with Common Core Standard HS.A-CED.A.3.\n
