Exercise 3 Page 160

Graph each inequality separately. The overlapping region will be the solution of the system.

Practice makes perfect
To solve the given system by graphing, we will first graph each inequality separately, then combine the graphs. The overlapping region will be the solution of the system.
Let's start!

Inequality I

To graph an inequality, we first determine its boundary line. By changing the inequality symbol to an equals sign, the boundary line can be determined.
Since the boundary line is not in slope-intercept form, we will rewrite it in slope-intercept form.
