The inequality is explained below.
Inequality is a statement of an order relationship between two numbers or algebraic expressions
In this vase, with a number line with two points opposite from each other on a number line, the middle of it is always going to be 0.
Therefore, both points are the same distance away from 0 just in opposite directions.
That means point Q is always going to equal the negative of point P. An example of this is if point p equals 5, point p equals -5.
This method only works when it is specifically stated that the two points are opposite from each other.
