Guided Notes

3 key concepts

  • 1

    To graph the inequality y ≤ 4x + 3, first graph the line y = 4x + 3, noting the y-intercept is 3 and the slope is 4, then shade the area below the line.

  • 2

    When graphing y > –x/2 – 6, graph the line y = –x/2 – 6 as a dashed line to show that the line itself is not included in the solution.

  • 3

    The solution set of an inequality includes all the points on the coordinate plane that satisfy the inequality, which can be a region above or below a line.
