Week 11 - Systems of Inequality

What two signs would give you a dashed or dotted line? 

• <, >
• ≤, ≥

When you graph an inequality, you used a solid line when you use which symbols?

• ≤, ≥ 
• <, >

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.

Consider the function y<2x+3. Which is true?

• The line would be solid with shading above.
• The line would be dashed with shading above.
• The line would be solid with shading below.
• The line would be dashed with shading down

What type of line and what way would you shade with the following sign? 
<

• Dotted, shaded up
• Dotted, shaded down
• Solid, shaded up
• Solid, shaded down

What type of line and what way would you shade with the following sign? 
≥

• Dotted, shaded up
• Dotted, shaded down
• Solid, shaded up
• Solid, shaded down

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

Which point below is NOT part of the solution set?

• (0, 0)
• (5,5)
• (3, 5)
• (0, -3)
