If the inequality includes 'or equal' then use a solid dot [the value is included]. If it doesn't use 'or equal' then use the open dot.

Which inequality symbols are represented by a solid line on a graph?

The graph of an inequality is a region, not a 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.


When will the graph of an equation inequality be a dotted line?

The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.


To graph the inequality is y less than or equal to negative 5x plus 3 you would draw a solid line?

When graphing an inequality with the symbol less than or equal to what is drawn?

if you have y <= f(x), then graph the function y = f(x) with a solid line, then shade everything below that graph.


How do you know where to shade on a graph?

If you mean with inequalities: 1. Change the inequality into an equation.2. Solve the equation for the initial line.3. Look back to the inequality.a.) greater than or equal to-shade above or to the left of your line,this line should be solidb.) greater than-shade above or to the left of your line,this line should not be solidc.) less than or equal to-shade below or to the right of your line,this line should be solidd.) less than-shade below or to the right of your line,this line should not be solidHope this helps.


How do you solve the inequality and graph a solution?

I think you would use an average two step equation to solve. Graph on a number line. If it was -2, go over 2 to the left, and make a dot. It is hollow or solid. It is solid if there is a line beneath the less than or greater than sign indicating that it is equal to....

What is the equal to or greater then symbol on a graph?

If the graph is a two-dimensional plane and you are graphing an inequality, the "greater than or equal to" part will be shown by two things: (1) a solid, not a dotted, line--this part signifies the "or equal to" option--and (2) which region you shade. Shade the region that contains the points that make the inequality true. By shading that region, you are demonstrating the "greater than" part.

If the line on a graph is solid the line is part of the solution true or false?

How do write the Slope-intercept inequality for a graph?

First, write the equation of the line of the graph. Next, if the line is solid, it means equal to. If it is dotted: not equal to. Lastly, the shaded portion of a graph is where the points satisfy the equation. So pick a point in the shaded region, plug it in, and put the appropriate larger than, or less than sign to make the statement true. EX: plug in (3,1) to y _ 3x+1 1 _ 10, then 1 < 10 So, y < 3x + 1 (add [or equal to] if the line is solid)


When graphing inequalities which inequality line is solid?

The line that includes whatever variables are included in the equation.


What will the line be if the inequality has a line underneath it?

If I understand the question correctly, the inequality is not strict. This means that points on the line are part of the solution and so the line is shown as a solid line rather than a dashed line.If I understand the question correctly, the inequality is not strict.

What does it mean when you have a solid dot on your graph?

It usually means that the end point is included in the range of values that you are intereted in. For example, a graph of 0 ≤ x < 1 would have a solid dot at 0 and a hollow circle at 1 while a graph of 0 < x ≤ 1 would have a hollow circle at 0 and a solid dot at 1.


Which inequalities have solid line and which ones have dashed lines?

Any line divides the Cartesian plane into two parts. When deciding whether the line should be solid or dashed, think of the points on the line. If these points are not in the permitted region then it will be a dashed line, otherwise it will be a solid line. Usually this will mean that a strict inequality is dashed.

When an inequality is graphed would you shade the line?

The line must be solid if the inequality is strict (less than or greater than). It must be a dashed line if otherwise (less than or equal to, greater than or equal to).


How do you graph inequalities in two variables?

to graph in equaltities in two variables, you graph the two numbers and/or variables. then you look at the sign to see if its greater than, less than, greater than or equal to, or less than or equal to and you graph the line as dashed or a solid


How do you graph the absolute value of x is less than or equal to 4?

use a line graph. Place a solid dot at 4. Shade the entire region to the left of 4.x is Less than shade Left.* * * * * The above answer is so very wrong - it has missed out the key word "absolute".Use a line graph. Put a solid dot at -4 and another solid dot at +4 and join them. Every point on the line (including the two end points) is the graph.


How would you know that the boundary line is enclosed in a graph?

The boundary line is solid. If not it will be a dashed line.
