Find the midpoint given the endpoints (4,-10) (22,-4) Please do not use space when
Elza [17]

Answer: (13,-7)

Step-by-step explanation:

By using the formula (x_{m},y_{m})  =(\frac{x_{1}+x_{2}  }{2},\frac{y_{1}+y_{2}  }{2} )

(x_{m},y_{m})\\ is the coordinates of the midpoint.

For finding the midpoint X variable do:

(\frac{4+22}{2})=13

For finding the midpoint Y variable do:

\frac{-10+(-4)}{2} = -7 (you can either keep the parenthesis or take them out. Either way, the answer is the same.

Considering coordinate numbers follow the format: (x,y), you'll simply just substitute the numbers found above into their respective places.

x: 13

y: -7

(13,-7).
