When graphing a linear inequality when can you NOT use (0 0) as a test point to determine which side of a boundary line to shade?

When the line goes through the origin like y>3x. Notice that there is no constant added to the end.

When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
How do you describe the steps for graphing a two-variable linear inequality?
Hi
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
When graphing inequalities where can solutions be found?
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.
How do you find a linear function?
By finding something who's behavior is represented by a linear function and graphing it.
When to use a solid line as a boundary when graphing a linear inequality?
If it is <= or >=
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 graphing a linear inequality what does a dashed boundary line inducarte?
The dashed boundary inducartes that the points on the boundary are not includedin the region which it bounds.This would be the case when the inequality says that one side is (more or less) than ...but not equal to ... the other side.
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 on a coordinate plane different from graphing an inequality on a number line?
The first is 2-dimensional, the second is 1-dimensional.
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 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.
Explain when to use a solid line as a boundary when graphing a linear inequality?
If the points that are ON the line satisfy the inequality then the line should be solid. Otherwise it should be dotted. Another way of putting that is, if the inequality is given in terms of ≤ or ≥, then use a solid line. If they are < or > use a dotted line.
Explain when to use a solid line as a boundary when graphing a linear in equality?
you use a solid line when the inequality is less than or equal to or greater that or equal to the dotted line is for less than or greater than
