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
![(15-8)/(2)=(7)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/tb7021evfznufneowom7mj3ixaxnwckq98.png)
y value
Its location on y is the average of the y values of the two given points: -17 and -8
![(-17-8)/(2)=(-25)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/ig27b65r4acww8xmj8kvr5qvqz9zdqqw6p.png)
Then, we have that
x=7/2
and
y=-25/2
Then, the midpoint's location is
(x, y) = (7/2,-25/2)
