Answer:
[tex]d=2\sqrt{17}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in your 2 coordinates into the distance formula to find distance d:
[tex]d=\sqrt{(-9-(-7))^2+(-8-0)^2}[/tex]
[tex]d=\sqrt{(-9+7)^2+(-8)^2}[/tex]
[tex]d=\sqrt{(-2)^2+64}[/tex]
[tex]d=\sqrt{4+64}[/tex]
[tex]d=\sqrt{68}[/tex]
[tex]d=2\sqrt{17}[/tex]
