Question

The midpoint of JK is point L at (-1,8). One endpoint is J (4, -15). Which equations can be solved to determine the coordinates of the other endpoint, K?

Answer 1

Answer:

( -6 , 31 )

Step-by-step explanation:

$\frac{(x + 4)}{2} = - 1 \\ \\ x + 4 = - 2 \\ \\ x = - 6 \\ \\ \frac{(y - 15)}{2} = 8 \\ y - 15 = 16 \\ \\ y = 31$
