Final answer:
The formula d=(x₂−x₁)²+(y₂−y₁)² represents the calculation of distance between two points in a two-dimensional plane.
Step-by-step explanation:
The formula given, d = (x₂−x₁)² + (y₂−y₁)², represents the calculation of distance between two points in a two-dimensional plane. It is derived from the Pythagorean theorem.
By finding the square root of the sum of the squares of the differences in the x and y coordinates between the two points, we can determine the distance between them.
