    How Do You Name a Set That's Graphed on a Number Line?

    If you have ever stared at a number line with dots on it and wondered 'How could I summarize these dots?', then this is the tutorial for you!

• Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
