if you have y <= f(x), then graph the function y = f(x) with a solid line, then shade everything below that graph.
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.
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
An inequality has no magnitude. A number can be greater than or equal to -5, but not an inequality.
an inequality
A dashed line is used when the equality is equal to and less than/more than. (≤, ≥) A solid line is used when the inequality is just less than/more than. (<, >)
With the equal sign (=).
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
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
The inequality symbol for less than or equal to: ≤
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.
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.
An inequality is not a reflexive relationship.
It means that the inequality is less than the value of the dashed line and is not equal to it.
Well, you can replace the inequality with the equal sign, and draw the line (or curve, depending on the case) for the corresponding equation. The actual inequality will be either to one side or to one side of this line or curve. It may or may not include the actual line or curve.
If you want that as an inequality, you write:x <= -10 You can replace "<=" with the corresponding inequality symbol (less than or equal).
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
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.
