If the mid-point is (6, 12) then the coordinate of the endpoint K is (2, 16). Then the correct option is A.
What is coordinate geometry?
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
Point J has coordinates (10,8). The midpoint of the line segment JK is (6,12).
Then we have The coordinate of K will be
[tex]\rm (x_2, y_2) = (2x - x_1 , 2y -y_1)\\\\(x_2, y_2) = (2\times 6- 10, 2 \times 12 - 8)\\\\(x_2, y_2) = (12-10 , 24-8)\\\\(x_2, y_2) = (2, 16)[/tex]
