The exact distance between two points (-2,-1) and (6,8) is = √145 units
= 12.042 units.
If two points on a plane is mentioned as (x₁, y₁) and (x₂, y₂), then the distance between them is √[(x₁ - x₂)² + (y₁ - y₂)²] units.
Give, two points are (-2,-1) and (6,8).
Therefore, the distance between them is
= √[(- 2 - 6)² + (- 1 - 8)²] units
= √[(- 8)² + (- 9)²] units
= √(64 + 81) units
= √145 units
= 12.042 units
