Answer:

[tex]\sqrt{61}[/tex]

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 = [tex]\sqrt{(-4-1)^2+(-1-5)^2}[/tex]

   = [tex]\sqrt{(-5)^2+(-6)^2}[/tex]

   = [tex]\sqrt{25+36}[/tex]

   = [tex]\sqrt{61}[/tex] ≈ 7.8 ( to 1 dec. place )
