$d\approx3.162 \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, $( 0,-5 ) \text{ and } ( 1,-2 ),$ is \begin{array}{l}\require{cancel} d=\sqrt{(0-1)^2+(-5-(-2))^2} \\\\ d=\sqrt{(-1)^2+(-3)^2} \\\\ d=\sqrt{1+9} \\\\ d=\sqrt{10} \\\\ d\approx3.162 \text{ units} .\end{array}
