Answer 1

To determine the distance between two points on a number line, you can use the formula:

\[
\text{Distance} = |x_1 - x_2|
\]

In this case, the two points are \( x_1 = -18.26 \) and \( x_2 = -2.45 \).

Calculating the distance:

\[
\text{Distance} = |-18.26 - (-2.45)| = |-18.26 + 2.45| = |-15.81| = 15.81
\]

So the distance between \(-18.26\) and \(-2.45\) on a number line is \(15.81\).

The correct response is:

**15.81**
