How can you check to see that you have shaded the correct half of the coordinate plane after graphing a linear inequality?

This is a simple thing to check. The inequality will either be y< or y> (less than y or greater than y). You know the area above the x-axis, where y=0, is where y is greater and the area below is where y is less. So the area above your graphed line is where y is greater and the area below your line is where y is less. This is easiest to check in a linear portion of your graph, i.e. the minimum or maximum point on a parabola.

How is graphing a linear inequality on a coordinate plane different from graphing an inequality on a number line?
The first is 2-dimensional, the second is 1-dimensional.
How is graphing an inequality different from graphing a line on a coordinate plane?
Whereas the procedure for a linear equality is the same, the inequality defines all of the plane on one side (or the other) of the corresponding line.
How is graphing a linear inequality different than graphing a linear equation?
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
How is graphing a linear inequality the same as graphing a liner equation?
They are alike in that you graph the lines in the same way, but they are different because you have to shade in one side of the line
What does a dashed boundary line indicate when graphing linear inequalities?
It means that the inequality is less than the value of the dashed line and is not equal to it.

When to use a solid line as a boundary when graphing a linear inequality?
If it is <= or >=
When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
How is graphing a linear inequality the same as graphing a linear equality?
Because the question is tautological. You are asking how something is the same as that very samne thing!
How do you describe the steps for graphing a two-variable linear inequality?

What is the feasible region in linear programming?
Linear programming is just graphing a bunch of linear inequalities. Remember that when you graph inequalities, you need to shade the "good" region - pick a point that is not on the line, put it in the inequality, and the it the point makes the inequality true (like 0
What does a dashed boundary line indicate when graphing linear inequalities?
It means that the inequality is less than the value of the dashed line and is not equal to it.
How is graphing a linear equality different from graphing linear equation?
They are the same.
