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

Given Coordinates: x₁ = -2  y₁ = -1,  x₂ = -1  y₂ = 4
Distance Formula: d = √(x₂ − x₁)² + (y₂ − y₁)²
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(-1 − (-2))² + (4 − (-1))²
d = √(-1 + 2)² + (4 + 1)²
d = √1² + 5²
d = √1 + 25
d = √26
Therefore, the distance between the points (-2, -1) and (-1, 4) is equal to √26
Note: As a decimal number, √26 ≈ 5.0990195135928
