whats the difference between x=-1and x=1?

1 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.
