How to tell inequalities apart by graphing them

               Todays blog post will be about why when you graph an inequality such as: <, >, <, and >. , you have to either put a closed dot or an open one. You only put an open dot when you don't have a line underneath the greater than or less than sign. You put a closed dot with the signs that have a line underneath  We do this so that we can tell the signs apart if they are different signs. You have to do this if you want everybody to see your point and were its located and if it is a less than or equal to or if it is a greater than or equal to. This is just something that you have to do in order to tell these signs:  <, >, <, and > apart from which way you are going.  This is the current lesson that we are learning in my Pre-Algebra class. It is not that hard if you know which inequality that you are using it is basically like greater than and less than, or >, <, but in a little bit harder way. You can also use these to form a problem like v+5>12 You would then subtract five from both sides. The problem would look like this 7v>7. All you do next is to do the opposite that it is telling you so that the number could cancel out, so it would look like this v=1. That is all that you do to solve a problem with inequalities, and this is how to tell them apart with a different way of graphing it.
