Question

Find the midpoint of the segment between the points (15,−17) and (−8,−8)A. (23/2,−9/2)B. (7,−25)C. (7/2,−25/2)D. (−7,25)

Answer 1

Midpoint

We want to find the midpoint between the points (15,−17) and (−8,−8):

We have that its location is (x, y).

We only find the average of each variable of the points:

x value

Its location on x is the average of the x values of the two given points: 15 and -8

$\frac{15-8}{2}=\frac{7}{2}$

y value

Its location on y is the average of the y values of the two given points: -17 and -8

$\frac{-17-8}{2}=\frac{-25}{2}$

Then, we have that

x=7/2

and

y=-25/2

Then, the midpoint's location is

(x, y) = (7/2,-25/2)
