Systems of Inequalities

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

• ≤, ≥ 
• <, >

Which point below is NOT a part of the solution set?

• (0, 0)
• (0, 1)
• (-100, -3)
• (5, 10)

Which point is a solution?

• (0, 6)
• (-3, 4)
• (1, 0)
• (-4, 3)

Which of the following is not a solution to this system of inequalities?

• (0,-1)
• (0,3)
• (4,0)
• (6,-2)

Is (0,0) a solution to the system?

• Solution
• Not a solution

This graph represents the inequality  y < 3, TRUE or FALSE?

• TRUE
• FALSE

The given graph represents the inequality  x < -1, TRUE or FALSE?

• TRUE
• FALSE

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.
• None of these.

When graphing an inequality, you use a dotted line when you use which symbol?

• <, >
• ≤, ≥ 

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.
