What is ...........the set of two or more linear inequalities involving the same variables x and y.

• Linear Function

• System of Linear Inequalities

• System of Equations

• Boundary Line

a line plotted on a coordinate graph that divides the graph (or plane) into two half‐planes. Can be dashed or solid.

• Linear Function

• Slope

• Y-Intercept

• Boundary Line

What is the definition for Linear Inequality?

•  

  the relationship between two values showing if one is less than, greater than, or simply not equal to another value. (<, >, ≤ or ≥)

   

   

   

• a function that represents a straight line on the coordinate plane.

• a mathematical expression in which two expressions are compared using the inequality symbol. Almost the same as a linear equation, except the equals sign is replaced with an inequality.

• the set of two or more linear inequalities involving the same variables x and y.
