Answer
Distance: $\sqrt{85}$
Midpoint: $M(-\frac{1}{2};2)$
Work Step by Step
The distance between two points can be calculated by the distance formula:
$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$
$d=\sqrt{(-4-3)^2+(5-(-1))^2}=\sqrt{(49+36)}=\sqrt{85}$
The midpoint can be calculated by the average of the x and y coordinates of the two points.
$M(\frac{3+(-4)}{2};\frac{-1+5}{2})= (-\frac{1}{2};2)$
