Answer

$\sqrt{41}$

Work Step by Step

To find the distance between two points $(x_1,y_1)$ and ($x_2$,$y_2$), we use the distance formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ We apply this to points $(-4,2)$ and $(-8,-3)$: $=\sqrt{(-8-(-4))^{2}+(-3-2)^{2}}$ $=\sqrt{(-4)^{2}+(-5)^{2}}$ $=\sqrt{16+25}$ $=\sqrt{41}$
