Graphing and Shading Inequality

When graphing an inequality, which symbols tell you to use a dashed line?

• <, >

• ≤, ≥

When graphing an inequality, which symbols tell you to use a solid line?

• <, >

• ≤, ≥

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

When graphing an inequality with the following symbol:

< or >

you should use a...

• solid line

• dashed line

• solid line

• dashed line

• A dotted line

• A solid line

• Shade up

• Shade down

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.
