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

midpoint just find the average of the x values and the average of the y values
the average of two numbers can be found by adding those numbers and dividing by 2 (you know since there are two numbers)

Answer 2

for example the average of the x's is given by (-15+(-4))/2

Answer 3

the length between the endpoints can be found by using the distance formula

Answer 4

\[d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\]

Answer 5

So after i finish solving for the formula I can get my answer or I have to do more?

Answer 6

the thing called d will give you the length when pluggin in the points
the average of the x's and the average of the y's will give you the midpoint

Answer 7

that is what your question ask to find is the midpoint and the length between the endpoints

Answer 8

ok thank you :D
