Chapter 1: Q. 2 (page 13)

If $- 3$ and 5 are the coordinates of two points on the real number line, the distance between these points is _________.

Short Answer

Expert verified

The distance between the given points is 8.

Step by step solution

Step 1. Given information.

The given statement is:

If and 5 are the coordinates of two points on the real number line, the distance between these points is _________.

Step 2. Determine the distance between two points.

Subtract the smaller number from the larger number.

$\begin{array}{rcl} 5 - (- 3) & = & 5 + 3 \\ = & 8 \end{array}$

We can use absolute value to calculate the distance between two points without being concerned about which is smaller.

$\begin{array}{rcl} |- 3 - 5| & = & |- 8| \\ = & 8 \end{array}$

Step 3. Conclusion.

The distance between the given points is 8.
