What's the first step to solving for y in

4x + 2y < 1?

• Add 4x to both sides of the inequality

• Subtract 4x from both sides of the inequality

• Divide every term by 4

• Divide every term by -2

What's the second step to solving for y in

2y < -4x + 1?

• Add 4x to both sides of the inequality

• Subtract 4x from both sides of the inequality

• Divide every term by -4

• Divide every term by 2

What's the first step to solving for y in

-8x - 4y ≥16?

• Add 8x to both sides of the inequality

• Subtract 8x from both sides of the inequality

• Divide every term by -4 and flip the inequality sign

• Divide every term by 8 and flip the inequality sign

What's the second step to solving for y in

-4y ≥ 8x + 16?

• Add 8x to both sides of the inequality

• Subtract 8x from both sides of the inequality

• Divide every term by -4 and flip the inequality sign

• Divide every term by 8 and flip the inequality sign

How confident do you feel about solving inequalities?

• I need to see the steps and examples for how to solve inequalities first.

• I feel confident that I understand them. I can move on to graphing inequalities.

• I'm not sure how I feel.
