Chapter 13.2, Problem 43SR

To determine

To find: the measurement of two points $AC$ using number line.

Answer to Problem 43SR

The measurement of $AC=5.$

Explanation of Solution

Given:

  

The coordinates of  $A$ and  $C$ are $-6$ and  $-1$ .

Concept used:

Distance should be put in modulus since, distance cannot be negative.

Difference in the coordinate is:

  $\text{higher value-lower value}$ .

Calculation:

The coordinates of  $A$ and  $C$ are $-6$ and  $-1$ .

Distance of the coordinate can be calculated as:

  $\text{higher value-lower value}$ and distance should be put in modulus since, distance cannot be negative.

  $AC=\left|-6-\left(-1\right)\right|=5.$

Hence, the measurement of $AC=5.$
