Are the points on the line part of the solution set or not? For example

• Yes, they are part of the solution set
• No, they are NOT part of the solution set

How can I tell if the graph of an inequality will have a solid line?

• It has just an equal sign.
• The symbol is greater than.
• The symbol has "or equal to."
• You just guess.
