Answer:
4
Explanation:
The distance formula is based on the Pythagorean theorem:
d² = (x₁ − x₂)² + (y₁ − y₂)²
(Notice the order doesn't matter.)
If we say (x₁,y₁) = (-6,-10) and (x₂,y₂) = (-2,-10), then the distance between the points is:
d² = (-6 − (-2))² + (-10 − (-10))²
d² = (-6 + 2)² + (-10 + 10)²
d² = (-4)² + (0)²
d² = 16
d = 4
