Answer
$d=17.8
\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, $(
8.6,-3.4
) \text{ and } (
-9.2-3.4
),$ is
\begin{array}{l}\require{cancel}
d=\sqrt{(8.6-(-9.2))^2+(-3.4-(-3.4))^2}
\\\\
d=\sqrt{(17.8)^2+(0)^2}
\\\\
d=\sqrt{17.8^2}
\\\\
d=17.8
\text{ units}
.\end{array}
