Question

Which inequality has a dashed boundary line when graphed ?

Answer 1

Answer:

Third inequality  has dashed boundary.

Step-by-step explanation:

An equality has dashed  boundary on graphing when it strictly less than or strictly greater than  Symbolically  ( <  or >   sign in the inequality)

boundary line is is solid line when the inequality is with symbol of equality also  ( < = or > = )

Here we can see that all the inequalities except third one has symbol less than or equal to or greater than or  equal to . And third inequality is with

symbol > (greater than ) that mean strictly less than ,therefore on graphing  

third inequality gives dashed line  boundary.
