The answer is B. Use distance formula...

[tex]d = \sqrt{(6 + 2) {}^{2} + (8 + 1) {}^{2} } [/tex]

The exact distance between two points (-2,-1) and (6,8) is = √145 units

= 12.042 units.

What is the distance between two points on a plane?

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
