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 &acirc;&permil;&curren; or &acirc;&permil;&yen;, then use a solid line. If they are &lt; or &gt; 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

How do you determine whether to use a solid or dashed line when graphing linear equation?

A dashed line is used when the equality is equal to and less than/more than. (&le;, &ge;) A solid line is used when the inequality is just less than/more than. (&lt;, &gt;)

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 "

When graphing inequalities which inequality line is solid?

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

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

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

State how to choose which half plane to shade when graphing an inequality?

It is standard procedure to shade the area where the Inequality does NOT apply, leaving the unshaded area to show where the Inequality is valid. Choosing a simple illustration, the Inequality y &gt; 6 would be graphically represented by a dotted line passing though y = 6 and parallel to the x-axis. The area below this line would be shaded as this represents the zone where y &lt; 6. Note : A broken/dotted line is used to illustrate the boundary where a true Inequality applies (e.g. &lt; or &gt;). A solid line is used where the Inequality also includes an equals sign (e.g. &le; less than or equal to, or &ge; greater than or equal to ).

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

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

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.

What is the independent variable when graphing the density of a solid?

Mass is the independent variable and should be plotted on the x-axis.

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.

How would you know if the endpoint of the graph of an inequality should be a solid dot or open dot?

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.
