Systems of Inequalities

When you graph the system:
y > -2x + 1
y≤ x + 3
Which of the following is a solution?

• (2, 0)
• (-1, 2)
• (0, 4)
• (0, -4)

This graph matches which inequality?

• y > 3
• y ≥ 3
• x≥3
• x>3

Graph:
y≤-2x+5
y>2x+7
Which of the following is NOT a solution?

• (-4, 2)
• (-10, 7)
• (-3, 0)
• (-2, 6)

Is (5, 2) a solution to the system?
2x+4y<20
3x-2y>11

• Yes
• No
• Sometimes

Which system of inequalities is shown?

• y ≥ -x - 1
  y < x + 4
• y < -x - 1
   y ≥ x + 4
• y > -x - 1
  y ≥ x + 4
• y > -x - 1
  y ≥ x + 3

Write an inequality represented by the graph.

• x < - 3
• y < - 3
• x > - 3
• x ≥ - 3

Tell whether the ordered pair 
(-3, 0) is a solution of the given system.
