Remember that
The formula to calculate the distance between two points is given by
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]we have the points
house (-6, 8) and the store (7, -1)
substitute the given coordinates in the formula above
[tex]\begin{gathered} d=\sqrt{(-1-8)^2+(7+6)^2} \\ d=\sqrt{81+169} \\ d=\sqrt{250} \\ d=16\text{ miles} \end{gathered}[/tex]therefore
