Answer:
15
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (2, 7) and (x₂, y₂ ) = (- 7, - 5)
d = [tex]\sqrt{(-7-2)^2+(-5-7)^2}[/tex]
= [tex]\sqrt{(-9)^2+(-12)^2}[/tex]
= [tex]\sqrt{81+144}[/tex]
= [tex]\sqrt{225}[/tex]
= 15
