Systems of inequalities #2

^{Which point is a solution to the system of inequalities?}

• (-8,2)

• (-2,-5)

• (0,6)

• (4, 3)

Which point below is NOT part of the solution set?

• (0, 0)
• (5, 1)
• (-1, -3)
• (20, -5)

Determine the ordered pair that IS a solution.

• (2, 2)
• (2, 4)
• (3, 2)
• (-3, 2)

Graph each system of linear inequalities and describe the solutions.
y > x + 1
y < x - 4

• Between the graphs
• above the graph y > x + 1
• below the graph y < x - 4
• No Solution

What's the difference between systems of equations and systems of inequalities?

• Systems of equations have 1 solution, no solution, or infinite solutions while systems of inequalities can have a range of solutions.

• Systems of equations use slope-intercept form only while systems of inequalities use standard form only.

• Systems of equations have a shaded region while systems of inequalities do not.

• There is no difference.

Which system of inequalities matches the graph?

• y > 2x - 4
  y < 2
• y < 2x - 4
  y < 2
• y > 2x - 4
  y <  2 
• y < 2x - 4
  y <   -2

Rewrite this inequality in "y=" form to graph. 
3x - 6y > 12

• y > ¹/₂x - 2
• y < -¹/₂x + 2
• y < ¹/₂x - 2
• y > -3x - 2

This system has an infinite number of solutions, TRUE or FALSE?

• TRUE
• FALSE

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

• ≤, ≥

• <, >

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

• <, >

• ≤, ≥
