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

• It has an equal sign.

• The symbol is greater than or less than.

• The symbol has "or equal to."

• You just guess.

Is the point (1, 2) a solution for the following inequality? Choose the best answer that has the best explanation.

• Yes because it is located in the shaded region.

• No because it is located on the line and the line is dotted.

• Yes because it is located on the line.

• No because it is in the shaded region.
