• y ≥ 3/5x - 5

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.

Select the correct graph for each inequality. y≤ -¾x -1

Select the graph for 5x+ y ≤  -1 .

• A
• B
• C
• D
