Answer 2

`(-15,9) \\ x_1=-15 \\ y_1=9 \\ \\ (-4,11) \\ x_2=-4 \\ y_2=11 \\ \\ \hbox{the length:} \\ l=√((x_2-x_1)^2+(y_2-y_1)^2)=√((-4+15)^2+(11-9)^2)=\\ =√(11^2+2^2)=√(121+4)=√(125)=√(25 * 5)=5√(5) \\ \\ \hbox{the midpoint:} ((x_1+x_2)/(2), (y_1+y_2)/(2)) \\ (x_1+x_2)/(2)=(-15-4)/(2)=(-19)/(2)=-9.5 \\ (y_1+y_2)/(2)=(9+11)/(2)=(20)/(2)=10 \\ (-9.5,10)`

The length of the segment is 5√5, the midpoint of the segment is (-9.5,10).
