Are you using MyMathLab or Course Compass as the software to do your homework? You should see a "palette" to be able to choose the open or filled-in circle. When the inequality includes the "equals to" line, you want the filled-in circle. You should be able to click it with your mouse, then click the spot on the graph. Let me know if you have any other problems/questions.

The line under < means "or equal to". If you are on a computer a filled in dot on the graph means to include that value... an open dot means up to that value... so if there is a line under it like this, < , you want a solid dot. Hope that helps.
