One & Two Step Inequalities

One & Two Step Inequalities

By the end of the lesson, you will be able to solve and graph one & two step inequalities.

​Solving & Graphing Inequalities

• Get out a piece of paper to complete the examples from the video.

• ​When you get to the question where you're prompted to pause, make sure to complete those on. your own and check your work with your neighbors and Mrs. Jackson.​

Multiple Choice

When do we switch the inequality symbol?

• when multiplying or dividing by a NEGATIVE

• when adding and subtracting a NEGATIVE

• we never switch the inequality

• When there is a negative in the problem

Multiple Choice

When graphing an inequality, you use an open dot when you use which symbol?

• <, >
• ≤, ≥ 

Multiple Choice

When graphing an inequality, you use a closed circle when you use which symbols?

• ≤, ≥

• <, >

Multiple Choice

Which inequality matches the graph?

• A

• B

• C

• D

Multiple Choice

Pick the correct letter for:
6 > x

• A
• B
• C
• D

Multiple Choice

Match the graph with its inequality.

• a > 11

• a < 11

• 11 ≤ a

• 11 ≥ a

Multiple Choice

The variable, k, is being divided by 11. How should you isolate the variable?  $$16=\frac{k}{11}$$  

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

Multiple Choice

y + 7 ≥ 12

• y ≥ 5
• y ≤ 5 
• y ≥ 19 
• y ≤ 19

Multiple Choice

Solve
8x < 48

• x < -6
• x > -6
• x < 6
• x > 6

Multiple Choice

What is the solution to the following inequality? $$3m-2>7$$  

• m > 3

• m < 3

• m = 3

• m > 5/3

Multiple Choice

Solve the inequality

• $$x<-6$$

• $$x\le-6$$

• $$x\ge-6$$

• $$x>-6$$
