2.12 Using Linear Inequalities as Constraints
This prepared you to write linear inequalities that represent constraints in situations and graphing the solution regions
Practice this chapterThis prepared you to write linear inequalities that represent constraints in situations and graphing the solution regions You graphed a related equation, interpreted the coordinate pairs of points on the graph and on either side of the graph, and tested the pairs of values to see if they make the inequality true.
You then used these observations to determine the solution region to the inequality You wrote an inequality that represents the constraints in a situation, graphed its solutions, and interpreted points in the solution region
Be able to interpret points in the coordinate plane and decide if they are solutions to the inequality, given a two-variable inequality that represents a situation; find the solutions to a two-variable inequality by using the graph of a related two-variable equation; write inequalities to describe the constraints in a situation.
