Key concepts students will learn:

•
When graphing inequalities with < or >, use an open circle, but when graphing ≤ or ≥, use a closed circle.
•
The phrase "no more than" translates to less than or equal to, while "at least" translates to greater than or equal to.
•
To solve inequalities with addition and subtraction, use the same steps as solving equations, but make sure to rewrite the inequality with the variable first.
