2.11 Graphing Linear Inequalities in Two Variables
The boundary between the two regions is the graph of an equation that is related to the inequality
Practice this chapterThe boundary between the two regions is the graph of an equation that is related to the inequality You also recalled that a linear equation in two variables has many solutions, which are represented by all the points on the graph of the equation
Decide if the values in each ordered pair, ( x , y ) , make the value of the expression less than, greater than, or equal to 12
boundary between the two regions — the graph of an equation that is related to the inequality.
Be able to determine which side of the line the solutions to the inequality will fall, given a two-variable inequality and the graph of the related equation; describe the graph that represents the solutions to a linear inequality in two variables; use the graphing tool or technology outside the course to graph each inequality. (The Desmos tool is provided).
