6.3 Introduction to Linear Inequalities

Inequalities We can use an inequality to model a situation that can be described by a range of numbers instead of a single number. These are the symbols we will be using…

What inequalities that represent these situations?

What inequalities represent these situations? What is the difference between an open and a closed circle?

Graph each of the following on a number line.
