Answer:
d ≈ 9.5
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (8, 2) and (x₂, y₂ ) = (- 1, 5)
d = [tex]\sqrt{(-1-8)^2+(5-2)^2}[/tex]
= [tex]\sqrt{(-9)^2+3^2}[/tex]
= [tex]\sqrt{81+9}[/tex]
= [tex]\sqrt{90}[/tex]
≈ 9.5 ( to the nearest tenth )
