Distance between points (3, 4) and (-1, 2)

Given Coordinates: x₁ = 3  y₁ = 4,  x₂ = -1  y₂ = 2
Distance Formula: d = √(x₂ − x₁)² + (y₂ − y₁)²
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(-1 − 3)² + (2 − 4)²
d = √(-4)² + (-2)²
d = √16 + 4
d = √20
d = √4 * 5
d = √4 * √5
d = 2√5
Therefore, the distance between the points (3, 4) and (-1, 2) is equal to 2√5
Note: As a decimal number, 2√5 ≈ 4.4721359549996
