Linear Inequalities

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.

Do I need to flip my sign?
2x -3y  ≥ 12

• Yes
• No

Which point below is NOT part of the solution set?

• (0, 0)
• (-10, -10)
• (-1, 5)
• (5, 20)

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

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