Guided Notes

3 key concepts

  • 1

    When solving inequalities, you can temporarily replace the inequality sign with an equal sign to find the boundary point.

  • 2

    After finding the boundary point, draw a number line and use an open or closed dot to represent whether the boundary point is included in the solution.

  • 3

    To determine which direction to draw the line on the number line, test a point that is not the boundary point in the original inequality; if the statement is true, shade towards the test point, and if it is false, shade away from the test point.
