Would appreciate your sharing actual inequalities to graph. Otherwise the topic is a bit broad.
Supposing you wanted to graph the inequality x<5:
Draw a dashed line through x=5, and then shade the area to the left of this line.
Supposing you wanted to graph the inequality x less than or equal to 5:
Draw a solid line through x=5, and then shade the area to the left of this line.
Please, respond with an inequality that you want to graph, and I'll help you with it.
