Solving and graphing a two step inequality

The video tutorial explains how to solve inequalities by treating them like equations. It emphasizes the importance of undoing addition and subtraction first, followed by multiplication or division. The tutorial also highlights the need to flip the inequality sign when multiplying or dividing by a negative number. Finally, it demonstrates how to graph the solution on a number line, using an open dot to indicate that the number itself is not included in the solution set.

What is the first step in solving an inequality?

• Add a constant to both sides

• Divide both sides by a constant

• Multiply both sides by a constant

• Undo addition or subtraction

When solving an inequality, what must you do if you multiply by a negative number?

• Keep the inequality sign the same

• Subtract the same number from both sides

• Flip the inequality sign

• Add the same number to both sides

What operation is used to undo division by a number in an inequality?

• Addition

• Division

• Subtraction

• Multiplication

How do you represent a solution on a number line when the inequality does not include equality?

• Use a closed dot

• Shade the entire line

• Use an open dot

• Draw a dashed line

In the context of graphing inequalities, what does an open dot signify?

• The number is included in the solution

• The number is not included in the solution

• The inequality is invalid

• The inequality is an equation
