Answer
$d=3$
Work Step by Step
RECALL:
The distance between the points $(x_1, y_1)$ and $x_2, y_2)$ can be found using the distance formula:
$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
Solve for the distance between the two points using the formula above to obtain:
$d=\sqrt{(0-\sqrt{7})^2+(-\sqrt{2}-0)^2}
\\d=\sqrt{(-\sqrt7)^2+(-\sqrt2)^2}
\\d=\sqrt{7+2}
\\d=\sqrt{9}
\\d=3$
