Pick a sample point in the shaded area and plug it into the equation and see if it makes it true.

What do the shaded dots refer to in the graph of an inequality?
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
In a nonlinear inequality which region represents the set of points that satisfy the inequality?
shaded
Which of the points listed would fall in the correct shaded area for the inequality?
The question asks about "listed" points. In such circumstances would it be too much to expect that you make sure that there is some list?
In a system of nonlinear inequalities the solution set is the region where the shaded regions overlap.?
The answer depends on which area is shaded for each inequality. I always teach pupils to shade the unwanted or non-feasible region. That way the solution is in the unshaded area. This is much easier to identify than do distinguish between a region which is shaded three times and another which is shaded four times.
True or false in the graph of a nonlinear inequality the xy-plane is divided into shaded and unshaded regions?
true

How is graphing a two variable inequality similar to graphing a one variable inequality?
One variable inequality- graph the point on the number line then choose a point on the point, to the left and to the right to see what gets shaded. Two variable inequality- graph the line on grid paper then choose a point on the line, to the left and to the right to see what gets shaded.
Why is a linear equation shaded?
Actually, a linear inequality, such as y > 2x - 1, -3x + 2y < 9, or y > 2 is shaded, not a linear equation.The shaded region on the graph implies that any number in the shaded region is a solution to the inequality. For example when graphing y > 2, all values greater than 2 are solutions to the inequality; therefore, the area above the broken line at y>2 is shaded. Note that when graphing ">" or "=" or "
How do you determine whether a parenthesis or a square bracket is used when graphing an inequality on a number line?
A parenthesis is used for a number which is an 'end' of an inequality but is not itself included. For example, if the inequality reads "x>3", there is an opening parenthesis on the hash-mark labelled '3', and the number line is shaded to the right. If the number IS included a bracket is used. So for -3 is less than or equal to x but less than 3, there is a [ on -3, and a ) on the 3, and the number line is shaded between -3 and 3.
In the graph of a linear inequality the shaded region above or below the line is called?
plane

How do you grid inequalities?
Graph as though the inequality is an equality. Then, find a point on one side of the line and see if it makes the inequality true. If it is true then that side gets shaded.
In the graph of a nonlinear inequality the xy-plane is divided into shaded and unshaded regions True of false?
True
In the graph of a linear inequality the shaded region above or below the line is called a?
it is called a half plane :)
