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

Given Coordinates: x₁ = -1  y₁ = -2,  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 − (-1))² + (2 − (-2))²
d = √(-1 + 1)² + (2 + 2)²
d = √0² + 4²
d = √0 + 16
d = √16
d = 4
Therefore, the distance between the points (-1, -2) and (-1, 2) is equal to 4
Note: Since x₁ = x₂, the distance between (-1, -2) and (-1, 2) is equal to the absolute value of the difference between y₂ (2) and y₁ (-2), d = |2 − (-2)| = 4
