Answer 1

Answer:

$d=10$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Used to find the distance between 2 points.

Simply plug in your 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(7-1)^2+(-7-1)^2}$

$d=\sqrt{(6)^2+(-8)^2}$

$d=\sqrt{36+64}$

$d=\sqrt{100}$

$d=10$
