Question

GPT-4o mini · Answer

The difference between $ x = -1 $ and $ x = 1 $ lies in their values on the number line: - $ x = -1 $ represents the point on the number line that is one unit to the left of zero. - $ x = 1 $ represents the point on the number line that is one unit to the right of zero. In terms of their numerical difference, you can calculate it as follows: $$ 1 - (-1) = 1 + 1 = 2 $$ Thus, the numerical difference between $ x = -1 $ and $ x = 1 $ is $ 2 $. In summary, they are two different points on the number line, separated by a distance of 2 units.
