Graphing Linear Inequalities

How can I tell if an inequality will have a solid boundary line?

• It has an equal sign.

• The symbol is greater than.

• The symbol has "or equal to."

• You just guess.

How can I tell if an inequality will have a dashed boundary line?

• It does not have an equal sign.

• The symbol is less than than.

• The symbol does not have "or equal to."

• You just guess.
