Answer 1

Answer:

D. $\sqrt{8}$

Step-by-step explanation:

We want to find the distance between (-6, 4) and (-8, 6).

First, we find the difference:

d = (-8 - (-6), 6 - 4)

d = (-8 + 6, 2)

d = (-2, 2)

We now find the magnitude:

$|d| = \sqrt{x^2 + y^2}$

where x = x coordinate, y = y coordinate

$|d| = \sqrt{(-2)^2 + (2)^2} \\\\|d| = \sqrt{4 + 4} = \sqrt{8}$

The answer is Choice D.
