#### Answer

$d=10
\text{ units}
$

#### Work Step by Step

Using $d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$ or the Distance Formula, the distance, $d$, between the given points, $(
0,8
) \text{ and } (
6,0
),$ is
\begin{array}{l}\require{cancel}
d=\sqrt{(0-6)^2+(8-0)^2}
\\\\
d=\sqrt{36+64}
\\\\
d=\sqrt{100}
\\\\
d=10
\text{ units}
.\end{array}
