Linear Inequalities.
Inequality- A mathematical statement comparing expressions that may not be equal these can be written using the symbols less that (<), greater than (>), less that or equal to.
Boundary Point- the point that separates the values less than from the values greater than a specified value. if its a possible value, it is closed circle on a number line. If it is not a possible value, the circle is open. For example, the boundary points for the inequality.
Solution of an inequality- A value or set of values that result in a true statement. The solution can contain a specific value or many values.

- Solve x + 3 < 0.
- If they'd given me "x + 3 = 0", I'd have known how to solve: I would have subtracted 3 from both sides. I can do the same thing here:
- Then the solution is:
- x < –3
