Exercise 45 Page 405

Graphing an inequality involves two main steps.

  1. Plotting the boundary line.
  2. Shading half of the plane to show the solution set.

Boundary Line

To graph the inequality, we have to draw the boundary line. The equation of a boundary line is written by replacing the inequality symbol from the inequality with an equals sign.
