What is Meant by Linear Inequalities?
In mathematics, a linear inequality is defined as the linear function with inequalities. The linear inequality function should possess any of the inequalities signs, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥) symbols. The linear function has one dependent variable and one independent variable. The linear inequality function can be classified into two types, namely:
- Linear Inequality in one variable
- Linear inequality in two variables
An example of a linear inequality is: -x+3 >2x+1
Graphing an inequality on a number line, is very similar to graphing a number. For instance, look at the top number line x = 3. We just put a little dot where the '3' is, right?
Now an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it.
Just remember- if the symbol is (≥ or ≤) then you fill in the dot, like the top two examples in the graph below
- if the symbol is (> or <) then you do not fill in the dot like the bottom two examples in the graph below
To better understand how to graph inequalities, look at the examples below or experiment with the grapher that is immediately below.
