Distance between points (9, 7) and (15, 13)

Given Coordinates: x₁ = 9  y₁ = 7,  x₂ = 15  y₂ = 13
Distance Formula: d = √(x₂ − x₁)² + (y₂ − y₁)²
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(15 − 9)² + (13 − 7)²
d = √6² + 6²
d = √36 + 36
d = √72
d = √36 * 2
d = √36 * √2
d = 6√2
Therefore, the distance between the points (9, 7) and (15, 13) is equal to 6√2
Note: As a decimal number, 6√2 ≈ 8.4852813742386
