Solving a simple one step inequality using division property of equality

The video tutorial explains how to solve a simple one-step inequality with a negative coefficient. It covers using inverse operations, flipping inequality signs when dividing by a negative number, rewriting inequalities with the variable on the left, and graphing the inequality on a number line. The tutorial emphasizes the importance of testing points and using open circles to represent inequalities that do not include the endpoint.

What must you remember to do when dividing or multiplying both sides of an inequality by a negative number?

• Keep the inequality sign the same

• Add the same number to both sides

• Flip the inequality sign

• Subtract the same number from both sides

If you have the inequality -16 < Y, how should it be rewritten to have the variable on the left?

• Y < -16

• Y > -16

• -16 > Y

• Y = -16

What analogy is used to help remember which side of the inequality is greater?

• The lion's mouth

• The alligator teeth

• The shark's fin

• The bear's paw

When graphing an inequality, what does an open circle on the number line indicate?

• The number is included in the solution

• The number is not included in the solution

• The inequality is false

• The inequality is true

Which of the following points would be a valid test point for the inequality Y > -16?

• -20

• -17

• -15

• -18
