Question

Find the midpoint of the segment between the points (1,1) and (4,−16).

A. (−5,15)
B. (5,−15)
C. (−3/2,17/2)
D. (5/2,−15/2)

Answer 1

D

Explanation:

The midpoint formula is

`M=((x_(1)+x_(2)  )/(2),(y_(1)+y_(2)  )/(2))`

Filling in our coordinates where they go gives us:

`M=((1+4)/(2),(1-16)/(2))` so

`M=((5)/(2),(-15)/(2))`
