Question

Find the distance between the pair of points. 1) (1,5) and (-4,-1)

Answer 1

Answer:

$\sqrt{61}$

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (1, 5) and (x₂, y₂ ) = (- 4, - 1)

d = $\sqrt{(-4-1)^2+(-1-5)^2}$

   = $\sqrt{(-5)^2+(-6)^2}$

   = $\sqrt{25+36}$

   = $\sqrt{61}$ ≈ 7.8 ( to 1 dec. place )
