The length of AB will be 10 units. Option B is corect. The formula for the distance between the two points is applied in a given problem.
<h3>What is the distance between the two points?</h3>
The length of the line segment connecting two places is the distance between them.
The distance between two places is always positive, and equal-length segments are referred to as congruent segments.
The given coordinate in the problem is;
(x₁,y₁)=(-2,-4)
(x₂, y₂)= (-8, 4)
The distance between the two points is found as;

Hence, option B is corect.
