Answer
$d=12.5$
M$(0,1\frac{1}{4})$
Work Step by Step
$d=\sqrt {(x_2-x_1)^2+(y_2-y_1)^2}$
$d=\sqrt {(6-(-6))^2+(-\frac{1}{2}-3)^2}$
$d=\sqrt {(12)^2+(-3\frac{1}{2})^2}$
$d=\sqrt {144+12.25}$
$d=\sqrt {156.25}$
$d=12.5$
M$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$
M$(\frac{-6+6}{2},\frac{3+(-\frac{1}{2})}{2})$
M$(\frac{0}{2},\frac{2\frac{1}{2}}{2})$
M$(0,1\frac{1}{4})$
