Find the distance between the two points (2,5) and (6,-1)

Reptile [31]

Answer:

= $\sqrt{52}$ units

Step-by-step explanation:

x₁ = 2 ; y₁ = 5

x₂ = 6 ; y₂ = -1

D = $\sqrt{(x₂ - x₁)² + (y₂ - y₁)²}$

= $\sqrt{(6 - 2)² + (-1 -5)²}$

= $\sqrt{4² + (-6)²}$

= $\sqrt{16 + 36}$

D = $\sqrt{52}$ units
