Answer E.

Explanation:

If A = (x₁, y₁) and B = (x₂, y₂):

d = √((x₂ - x₁)² + (y₂ - y₁)²)

A = (5, 6)

x₁ = 5, y₁ = 6

B = (-3. 2)

x₂ = -3, y₂ = 2

d = √((-3 - 5)² + (2 - 6)²)

d = √((-8)² + (-4)²)

d = √(64 + 16)

d = √80

Hi there!

We know our standard distance formula, . This is derived from the Pythagorean's theorem, as we can imagine there being a right triangle and finding the hypotenuse for the distance (See the attached graph).

Plugging these points in, we get:

Thus, we know the answer is E, the square root of 80.

Hope this helps!
