If the signnn is less than then it is below the line , if it is more than than it is above the line, that is the shaded region, If the signnn is less than then it is below the line , if it is more than than it is above the line, that is the shaded region,

When graphing a linear inequality in two variables how do you know if the inequality represents the area above the line?

Take a sample point from either the top or bottom of the graph. I like to use (0,0) if it is not on the line. Substitute it into the inequality and if it is true then it represents all points on that line as true and vice versa.


How do you know weather to shade above or below the line when graphing an inequality on the coordinate plane?

If the inequality has a > or ≥ sign, you shade above the line. If the inequality has a < or ≤ sign, you shade below it. Obviously, just an = is an equation, not an inequality.


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.


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 "


In the graph of a linear inequality the shaded region above or below the line is called?

plane


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&lt; or y&gt; (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.


In the graph of a linear inequality the shaded region above or below the line is called a?

it is called a half plane :)


What is a linear inequation?

A linear inequation is a line whose answers can be defined as anything on the line or anything below or above it. Just imagine it as a linear equation, except with an inequality sign.For example:1/2X + 2 >/= 4X >/=4The answer to this inequality is 4 or anything greater than 4.NOTE:- If the coefficient of X [or in any inequality problem, the coefficient of the X with the largest exponent] is negative, flip the inequality symbol.For example:-X^3 + 8 > 0-X^3 > -8-X > -2x < 2The answer to the above inequality is anything less than 2.Always check your answer!


How are linear equations and linear inequalities similar?

A linear equation corresponds to a line, and a linear inequality corresponds to a region bounded by a line. Consider the equation y = x-5. This could be graphed as a line going through (0,-5), (1,-4), (2,-3), and so on. The inequality y &gt; x-5 would be the region above that line.


Solve the inequality 3 -2 x 7.?

The above is not an inequality as stated.


Can Lorenz curve above the diagonal?

No.The Lorenz curve measures inequality of distribution of income (or wealth). The diagonal represents a distribution that is perfectly equal and you cannot get more equal than that!


Where is the region of the graph of the linear inequality y is greater or equal to 2x-1?
