Question

the midpoint of KL is M(5, -7). One endpoint is K(9, -7). Find the coordinates of the other endpoint L.

Answer 1

well if we have two points \[(x_1,y_1) \text{ and} (x_2,y_2)\]

Answer 2

then

Answer 3

maybe you can try to plot the points on Cartesian Coordinate... :)

Answer 4

\[midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})\]
