Answer
$d(A, B)=\sqrt{41}$
Work Step by Step
The distance $d$ between the points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula:
$$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$$
Use the formula above to obtain:
$d(A, B)=\sqrt{(-4-(-8))^2+(2-(-3))^2}
\\d(A, B)=\sqrt{(-4+8)^2+(2+3)^2}
\\d(A, B)=\sqrt{4^2+5^2}
\\d(A, B)=\sqrt{16+25}
\\d(A, B)=\sqrt{41}$
