The Distance Formula helps us find the length between two points in a coordinate plane. The formula is written as d = √((x₂ - x₁)² + (y₂ - y₁)²), where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points. To use the formula, subtract the x-coordinates and the y-coordinates of the two points, square those differences, add them together, and then take the square root of the sum. For example, if we have points A(1, 2) and B(4, 6), we first find the differences: (4 - 1)² and (6 - 2)². This gives us 3² + 4², which equals 9 + 16. Finally, we take the square root of 25, resulting in a distance of 5 units between points A and B. This formula is useful in many real-life situations, such as navigation or architecture.
