Solving Systems of Inequalities by Graphing

What is the main difference between systems of inequalities and systems of equations?

• Systems of equations have no solutions.

• Systems of equations have multiple solutions.

• Systems of inequalities have multiple solutions.

• Systems of inequalities have one solution.

Why did the first ordered pair not work in the system of inequalities?

• It worked in the bottom inequality but not the top one.

• It worked in the top inequality but not the bottom one.

• It worked in both inequalities.

• It did not work in either inequality.

What is the y-intercept of the first inequality in the first system?

• 3

• 2

• 1

• 0

What type of line is used for the inequality 'y < 2x'?

• Double line

• Thick line

• Dashed line

• Solid line

In the first system, where do you shade for the inequality 'y < x + 1'?

• To the left of the line

• On the line

• Below the line

• Above the line

What is the y-intercept of the second inequality in the second system?

• 3

• 0

• 1

• -2

For the inequality 'y ≥ -x - 2', where do you shade?

• Below the line

• Above the line

• To the left of the line

• On the line

When graphing in standard form, what is the x-intercept of the inequality '3x + y > -3'?

• 1

• -1

• 3

• -3

What type of line is used for the inequality 'x ≤ 4'?

• Solid line

• Dashed line

• Thick line

• Double line

In the final example, where do you shade for the inequality 'y ≤ 2'?

• Above the line

• To the left of the line

• Below the line

• On the line
