$d=10 \text{ units} $

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}
