Graphing Linear Inequalities

Are the points on the boundary 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

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

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

y ≥ -2x - 2 will have what type of line

• dashed

• solid

y ≥ -2x - 2 will be shaded

• above

• below

y < x - 2 will have what kind of line?

• dashed

• solid

y < x - 2 will be shaded

• above

• below
