Answer:
Explanation:
The midpoint between two points is the average of the coordinates.
mp=((x2+x1)/2, (y2+y1)/2)
In this case we are given one end point and the midpoint.
Just look at the x coordinate first.
If the mid x is 8 and the x from j is 10 we have
(10+x)/2=8
10+x=16
x=6, now for the y for j when y=6 and mid y of 5
(6+y)/2=5
6+y=10
y=4
So the coordinates of K are (6,4)
