Question

Determine the length and midpoint of the segment whose endpoints are (–15, 9) and (–4, 11).
A.
length = 11.18, midpoint = (–5.5, 1)
B.
length = 11.18, midpoint = (–9.5, 10)
C.
length = 26.17, midpoint = (–5.5, 1)
D.
length = 26.17, midpoint = (–9.5, 10)

Answer 1

please help):

Answer 2

use distance formula for lenghth\[\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]

Answer 3

length*

Answer 4

and then use the midpoint formula\[\left( \frac{ x _{1} +x _{2}}{ 2 } , ~\frac{ y _{1} +y _{2}}{ 2 }\right)\]
