**In this lesson you will learn to write an inequality given a**number line representation.**A variable is a letter or symbol that represents an unknown**number or set of numbers. For example, x or ★ could be used to represent unknown numbers. An inequality has more than 1 solution.**represents:**An open circle > greater than < less than represents: A closed circle ≥greater than or equal to ≤ less than or equal to**The highlighted numbers are part of the solution set of the**inequality. x could equal 2.3, 5, 10, 13½, 30, 500…**1.

Flip the top card and the first player to write the inequality correct keeps the card. The player with the most cards wins.**What inequality represents the number line below?**• x ≤ 1 • x ≤ -1 • x ≥ 1 • x <1**What inequality represents the number line below?**• x > -9 • x ≥ -9 • x > -11 • x <-11
