$d=6.5$ M$(1\frac{3}{4},2)$

Work Step by Step

$d=\sqrt {(x_2-x_1)^2+(y_2-y_1)^2}$ $d=\sqrt {(3-(\frac{1}{2}))^2+(-1-5)^2}$ $d=\sqrt {(2\frac{1}{2})^2+(-6)^2}$ $d=\sqrt {6.25+36}$ $d=\sqrt {42.25}$ $d=6.5$ M$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$ M$(\frac{\frac{1}{2}+3}{2},\frac{5+(-1)}{2})$ M$(\frac{3\frac{1}{2}}{2},\frac{4}{2})$ M$(1\frac{3}{4},2)$
