Length of line segment (essentially distance between the two points) is 2

#### Explanation:

The length of this line segment is essentially going to be the distance between the two points, so we can use the distance formula. NOTE: If the distance formula seems foreign to you, it is essentially an application of the Pythagorean Theorem.

Distance Formula:

Now, let's plug in:

Our distance (essentially the length of our line segment) is 2. Notice, I only took the principal (positive square root) of 4. Reason being, distance is never negative, so we can ignore the negative square root.
