Answer
Distance: $\sqrt{202}$
Midpoint: $M(-\frac{5}{2};-\frac{5}{2})$
Work Step by Step
The distance between two points can be calculated by the distance formula:
$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$
$d=\sqrt{(3-(-8))^2+(-7-2)^2}
\\d=\sqrt{(121+81)}
\\d=\sqrt{202}$
The midpoint can be calculated by the average of the x and y coordinates of the two points.
$M(\frac{-8+3}{2};\frac{-7+2}{2})= (-\frac{5}{2};-\frac{5}{2})$
