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

Given Coordinates: x₁ = -1  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 − (-1))² + (4 − (-1))²
d = √(-1 + 1)² + (4 + 1)²
d = √0² + 5²
d = √0 + 25
d = √25
d = 5
Therefore, the distance between the points (-1, -1) and (-1, 4) is equal to 5
Note: Since x₁ = x₂, the distance between (-1, -1) and (-1, 4) is equal to the absolute value of the difference between y₂ (4) and y₁ (-1), d = |4 − (-1)| = 5
