Whats the difference between a dotted line and a solid line when graphing inequalities?
If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line. This line divides the xy- plane into two regions: a region that satisfies the inequality, and a region that does not.
What is the difference between a solid and dashed boundary line?
The boundary line for the inequality is drawn as a solid line if the points on the line itself do satisfy the inequality, as in the cases of ≤ and ≥. It is drawn as a dashed line if the points on the line do not satisfy the inequality, as in the cases of < and >.
What is the meaning of a dashed line in a graph?
1. A dashed line means that the solution is not a part of the inequality given and a solid line/regular line implies that the solution is a part of the inequality. For instance the inequality x\leq 3 when graphed gives a solid/regular line. This is because x = 3 is also a part of the solution to the inequality.
What is the difference between the solid line and the wavy line on a graph?
A solid line indicates that the bond exists in the plane of the drawing surface. A wavy line indicates that the stereochemistry of the bond is unknown.
How did you know if the boundary line is dashed or broken?
If the problem includes where it is equal, then you will have a solid boundary line. In other words, if you have < or > , you will have a solid line for your boundary line. If the problem does not include where it is equal, then you will use a dashed boundary line.
What is the difference between the broken line and solid line in sketching the parabola?
If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line. Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary.
What does dashed line mean in chemistry?
(chemistry) A method of representing the three-dimensional structure of a molecule in which simple lines represent bonds in the plane of the image, wedge-shaped lines represent bonds towards the viewer, and dashed lines represent bonds away from the viewer.
When to draw a dashed line or a solid line?
In this case you draw the line dashed to indicate that the line itself is not part of the solution. If the inequality is not strict (<=), then the line is part of the solution and it is drawn solid. 25 insanely cool gadgets selling out quickly in 2021.
Why is the line solid when the inequality is greater than?
Note that the line is solid because the inequality sign is greater than or equal to. Step 3: Shade the solution set. Since y is greater than the expression, shade the side “above” the line. If you are unsure, pick a “test” point to determine which side of the line you should shade to show the solutions to the inequality.
How to determine if a graph is dotted or solid?
Think of: y = 2x + 2 when you create the graph. Remember to determine whether the line is solid or dotted. In this case, since the inequality symbol is less than (<), the line is dotted. The points on the line are NOT solutions!
What to look for in graphing inequalities?
There are a few things to notice here. First, look at the dashed red boundary line: this is the graph of the related linear equation x= y x = y. Next, look at the light red region that is to the right of the line. This region (excluding the line x= y x = y) represents the entire set of solutions for the inequality x> y x > y.
