Mr. Black’s Math Class

EQ: How do I graph linear inequalities in one variable?

BR: Solve each equation.

1. 5x – 7 = -12
2. 6 = 3 – x
3. 
4. 8x = -32

Lesson:

1. Discuss BR.
2. What is an inequality? (Discuss >, <, ≤, ≥.)
3. Discuss graphing inequalities in one variable.
• x < 2
• x > -2
• x ≤ 1
• x ≥ 0
• –x >1
• –x ≤ -4
• –x > -4
4. Word Problems.
   Sue ran a 2-kilometer race in 8 minutes. Write an inequality to describe the average speeds of runner who were faster than Sue. Graph the inequality.

   Abu was sure that he didn’t score less than 3 on his algebra test. Write an inequality to describe Abu’s possible score. Graph the inequality.
