2.15 Solving Problems with Systems of Linear Inequalities in Two Variables
Making comparisons prompted you to think about the solutions to the equations, inequalities, or systems that were represented.
Practice this chapterMaking comparisons prompted you to think about the solutions to the equations, inequalities, or systems that were represented. Compare each of the following graphs, then list a reason for each graph why it would not belong with the other three
Your answers may vary,, but here are some samples
Be able to explain how to tell if a point on the boundary of the graph of the solutions to a system of inequalities is a solution; graph A is the only set of graphs that represents a system of equations. It is the only system with exactly one solution; graph B is the only set of graphs that represents a system of inequalities with no solutions.
