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

Given the system, determine a solution.

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

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

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

Given the graph, determine which is NOT a solution.

• (0, 0)
• (2, -1)
• (-2, -2)
• (-5, 1)

Determine the ordered pair that IS a solution.

• (2, 2)
• (2, 4)
• (3, 2)
• (-3, 2)

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

• Yes
• No
• Sometimes

Do I need to flip my sign?
2x -3y  ≥ 12

• Yes
• No

Select the graph for y ≥ -3.

• A
• B
• C
• D

Which system of linear inequalities is represented by the graph?

• y≤2x-1
  y>-2x+3
• y>2x-1
  y≤-2x+3
• y<2x-1
  y≥-2x+3
• y≤2x-1
  y>2x+3
