Linear Inequality & Absolute Value Review

An inequality using a > or a < has a ___________ line

• invisible
• solid
• dashed

Is (3,-4) a solution to this system?

• yes
• no

Pick the ordered pair that is NOT a solution

• (0,0)
• (1,-1)
• (2,0)
• (4,-4)

Match the system to the graph (solution set is on the left)

• y ≤ 3x   and  y ≤ -2x + 4
• y > 3x   and  y > -2x + 4
• y < 3x   and  y > -2x + 3
• y > 3x   and  y < -2x + 4

Which system of inequality is shown?

• y > -1/5x - 1/2  
   y ≥ -2x - 4
• y > -1/5x - 1/2  
   y ≤ -2x - 4
• y ≥ -1/5x - 1/2
   y ≤ -2x - 4
• y < -1/5x - 1/2  
  y ≥ -2x - 4

Solve the system of inequalities by graphing.

• 
• 
• 
• 

Given the system, determine a solution.

• No solution
• Infinite solutions
• (-5, 5)
• (5, -5)

The reason (2, 0) is NOT a solution is because ​ (a)  

• it is on the dotted line.
• it is in the shaded region.
• it is an intercept.
• it doesn't work.
• False, it is a solution. Don't try to trick me!

• (0,0)

• (-1,-3)

• (-2,-5)

• (0,-3)

• (1,-6)

Solve for x
l x−6 l + 4= 10

• x = 12 and x = 0
• x = 3 and x = -3
• x = -12 and x = 0
• No Solution
