The midpoint of jk jk is m(6, 3)m(6, 3). one endpoint is j(14, 9)j(14, 9). find the coordinates of endpoint k

In general if we have two end points as and

So we can find mid point of these two points by using below formula as

x - co-ordinate of mid point is


y - co-ordinate of midpoint is


So in given question let co-ordinate of point k is (a , b).
Co-ordinate of j is given as (14 , 9)

So we can find x co-ordinate of midpoint of jk is
 
Where and
x co-ordinate of midpoint is given as x = 6





We can find y co-ordinate of jk as


Where and
y co-ordinate of midpoint is  3.




SO co-ordinate of k point is (-2 , -3).

Lol idk ask google. ejie
