Which inequality represents John's goal if D is the number of dollars in his bank account?

• D > -7

• D ≤ -7

• D < -7

• D ≥ -7

How do you graph the inequality X ≥ 0?

• Open dot on 0, arrow to the left

• Open dot on 0, arrow to the right

• Filled dot on 0, arrow to the right

• Filled dot on 0, arrow to the left

What does a filled boundary point indicate in an inequality graph?

• The number is not part of the solution

• The number is part of the solution

• The inequality is strict

• The inequality is not strict

How do you graph the inequality X > 2?

• Open dot on 2, arrow to the left

• Filled dot on 2, arrow to the right

• Open dot on 2, arrow to the right

• Filled dot on 2, arrow to the left

What does an open boundary point indicate in an inequality graph?

• The number is not part of the solution

• The inequality is strict

• The inequality is not strict

• The number is part of the solution

If a graph shows a filled boundary point on -3 with an arrow pointing to the right, what inequality does it represent?

• X < -3

If a graph shows an open boundary point on 2 with an arrow pointing to the left, what inequality does it represent?

• X < 2

• X ≥ 2

• X ≤ 2

• X > 2
