Answer:

The answer is

<h2>2 \sqrt{26}  \:  \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points of a line segment can be found by using the formula

d =  \sqrt{ ({x_1 - x_2})^{2} +  ({y_1 - y_2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

P(-4, -2) and Q(-6, 8)

The length of the line segment is

|PQ|  =  \sqrt{ ({ - 4 + 6})^{2} +  ({ - 2 - 8})^{2}  }  \\  =  \sqrt{ {2}^{2}  +  ({ - 10})^{2} }  \\  =  \sqrt{4 + 100}  \\  =  \sqrt{104}  \:  \:  \:  \:  \:  \:  \:  \\  = 2 \sqrt{26}  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

2 \sqrt{26}  \:  \:  \:  \: units

Hope this helps you
