It means that the inequality is less than the value of the dashed line and is not equal to it.
The first is 2-dimensional, the second is 1-dimensional.
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.
When graphing inequalities you use a circle to indicate a value on a graph. If the value is included in the solution to the inequality you would fill in the circle. If the value that the circle represents is not included in the solution you would leave the circle unshaded.
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
strict inequality
If it is <= or >=
It means that the inequality is less than the value of the dashed line and is not equal to it.
its different because they both repersent something.
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.
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 a line you simply plot the points based on the ordered pairs and connect the dots; there you have a line. An inequality graph refers to the shaded region of the coordinate plane that does not coincide with the line, hence the term, inequality.
The first is 2-dimensional, the second is 1-dimensional.
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
