Can somebody please show me how to graph inequalities? I don't get it and my homework is way late so please HELP!

x>4 - graph the solution for each set of inequalities

3x[U]>2x-4 - solve and graph the solution set of each inequalities

I just need for someone to show and explain how to do these and I can try to do the rest on my own. Any help will be greatly appreciated THANKS
