Question 2: How do you graph a linear inequality?

To graph a linear inequality, first graph the corresponding equation as a line, then shade the appropriate region based on the inequality symbol (e.g., above the line for greater than, below for less than).

Question 3: What does a dashed line indicate in graphing inequalities?

A dashed line indicates that the points on the line are not included in the solution set (used for "<" or ">").

Question 4: What does a solid line indicate in graphing inequalities?

A solid line indicates that the points on the line are included in the solution set (used for "≤" or "≥").
