Given:
The position coordinates of the subway stop, (x1, y1)=(-7,3).
The position coordinates of the house, (x2,y2)=(-2,9).
The distance between the house and the subway stop is,
[tex]\begin{gathered} D=\sqrt[]{(x2-x1)^2+(y2-y1)^2} \\ =\sqrt[]{(-2-(-7))^2+(9-3)^2} \\ =\sqrt[]{(5)^2+6^2}^{} \\ =\sqrt[]{61} \\ \cong8\text{ } \end{gathered}[/tex]
Therefore, the distance between the house and the subway stop is 8 units.
Hence, option B is correct.
