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.

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 "
What is graphing proportions?
Graphing proportions is to take two ratios and plot them on an (x,y) coordinate plane. You need to be consistent with your labeling. If you use the numerator of one ratio as your x coordinate, then the numerator of the other ratio must be the 2nd x coordinate. You can graph as many of these points as are given. If your ratio's are proportional then you will have a straight line. If it is not a straight line when graphed your ratios are not proportional.
How can you name a point on a graph?
Compare it's position to the origin. The x coordinate is the number of units to the right of the origin. (If it is to the left of the origin the x coordinate is negative.) The y coordinate is the number of units above the origin. (If it is below, the y coordinate is negative.) The point is denoted (x,y) with the x coordinate in place of the x and the y coordinate in place of the y.
Givin the coordinate of one endpoint of segment AB and its midpoint find the coordniates of the other endpoint?
If the coordinate of A is x, and that of the midpoint of AB, M, is m then the distance AM is m-x so the distance AB = 2*(m-x) So the coordinate of B is x + 2*(m-x) = 2m-x For coordinates in more than one dimension, apply the above rule separately for each dimension.
Which side of the line do you shade with inequality signs?
Whichever side contains all the numbers that satisfy the inequality. Generally, "greater than" points to the right side of the line or above it, and "less than" will lead to the left side or below it. But you have to be careful, and it would really help a lot if you understood the whole concept better than you presently do.
When graphing a linear inequality how do you know if the inequality represents the area below or above the line?
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.
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.
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.

Solve the inequality 3 -2 x 7.?
The above is not an inequality as stated.
How are altitude and stars related?
Defining a stars location is done with a coordinate system just as one would use a X & Y system for graphing. Locating a star involves what compass direction the star can be found (azimuth) and how high above the visible horizon (altitude).

How do you find the point that two equations intersect?
If the equations are in y= form, set the two equations equal to each other. Then solve for x. The x value that you get is the x coordinate of the intersection point. To find the y coordinate of the intersection point, plug the x you just got into either equation and simplify so that y= some number. There are other methods of solving a system of equations: matrices, substitution, elimination, and graphing, but the above method is my favorite!

Solve the following inequality 38 4x3 plus 7-3x?
To solve the above inequality equation it has to have an equality sign so that i group all the the knowns and the unknowns.
