Graphing linear inequalities
A straight line is drawn on a graph and one side of it is shaded. The student picks every inequality, such as 3x + 6y < 5, that describes the shaded region.
Several choices can be right, because an inequality can be scaled or rearranged (multiplying by a negative flips the sign). Whether the line is dashed or solid decides between < and ≤.
