I think that you are asking about the linear inequalities with two variables, so my answer is related to them.
First, you have to draw the boundary line (be careful, if your inequality does not contain the equal sign, the boundary line will be a dashed line, because the points on the line are not solutions to the inequality), which divide the coordinate system in two half-planes.
Second, you have to test a point on either sides of the line (the best point is the origin, (0, 0), if it is not on the boundary line). If that point satisfies the inequality, then there are all its solutions, otherwise they are to the opposite side.

When graphing inequalities why do you shade the graph?
The part that is shaded represents all the possible solutions. An inequality has solutions that are either left or righ, above or below or between two parts of a graph.
When graphing a system of inequalities the line is dotted for the?
strict inequality
When graphing inequalities when do you have a closed circle?
When the value indicated by the circle is a valid value for the inequality.
Does inequalities sometimes have real number solutions?
Yes, they can.
Why is graphing the solutions of an inequality is more efficient than listing all the solutions of the inequality?
because writing out all the solutions is not necessarliy a correct answer but a number line is and because graphing out also helps you get a mental image of the concept.

When is slope-intercept form useful?
its useful in graphing! equations, inequalities, ect pretty much graphing!
When graphing a system of inequalities the line is dotted for the?
strict inequality
What are the three steps to graphing inequalities?
-5+8n<-101
What is the definition of equivalent inequalities?
The definition of equivalent inequalities: inequalities that have the same set of solutions
Why is graphing a systems of inequalities a good way to show the solution set?
tty
Do solutions to systems of linear inequalities satisfy both inequalities?
Yes.
When graphing inequalities when do you have a closed circle?
When the value indicated by the circle is a valid value for the inequality.
Must solutions to systems of linear inequalities satisfy both inequalities?
Yes.
Do solutions to systems of linear inequalities need to satify both inequalities?
If it is joined by an "and" it does. If it is joined by an "or" it does not.
When graphing inequalities which inequality line is solid?
The line that includes whatever variables are included in the equation.
How many solution sets do systems of linear inequalities have. Must solutions to systems of linear inequalities satisfy both inequalities. In what case might they not?
There is only one solution set. Depending on the inequalities, the set can be empty, have a finite number of solutions, or have an infinite number of solutions. In all cases, there is only one solution set.
