Meets NCTM Standards:

Learn how to solve linear inequalities and graph them on a number line.
  • How do you solve inequalities?
  • How do you solve 4y - 3 < 5y + 2?
  • How do you rewrite -5 < y so y is on the left side?
  • How do you graph a linear inequality on a number line?
  • How do you know if you should draw a closed dot or an open circle at a value on a number line?
  • How do you solve 12 >= -0.3p?
  • What happens when you multiply or divide an inequality by a negative number?
  • How do you know which way to shade an inequality?
  • Why do you flip an inequality sign when you multiply or divide by a negative number?
  • How do you solve 10 <= 3y - 2 < 19?
  • How do you solve a compound inequality?
  • How do you graph a compound inequality on a number line?
  • How do you graph 4 <= y < 7 on a number line?
  • How do you solve the two inequalities x + 3 < 2 or -x >= -4?
  • How do you graph two inequalities combined with or on a number line?
  • How do you graph the solution set to x < -1 or x <= 4 on the same number line?
This lesson explains each step in a few different example problems of solving an inequality and graphing the solution set on a number line. As the lesson moves on, the inequalities get a bit more complicated, but all steps are still explained and shown.
