$\sqrt{73} \text{ units OR }\approx 8.544 \text{ units} $

Using the Distance Formula, $d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$, the distance between the given points is \begin{array}{l} \sqrt{(-1-2)^2+(5-(-3))^2} \\\\= \sqrt{9+64} \\\\= \sqrt{73} \text{ units OR }\approx 8.544 \text{ units} .\end{array}
