Graphing Inequalities on the Coordinate Plane

Today we looked at inequalities and how they are displayed on the coordinate plane. We first looked at inequalities written in standard form. After converting these equations, we determined the x and y intercepts of the line. We plotted the points and then determined whether the line should be dotted ( < or > ) or solid ( ≤ or ≥ ). Once the line is on the graph, we used a test point (I suggested using the origin whenever possible) to see which side of the line should be shaded.

Students completed 4 sample problems in class.
