Question

Find the other endpoint of the line segment if:
midpoint: (-10, -6) and one of the endpoints is: (-5, 4)

Answer 1

Answer:

( - 15, - 16 )

Step-by-step explanation:

Coordinates of midpoint are ( $\frac{x_{1} +x_{2} }{2}$ , $\frac{y_{1} +y_{2} }{2}$ )

( - 5 + x ) / 2 = - 10 ⇒ x = - 15

( 4 + y ) / 2 = - 6 ⇒ y = - 16

( - 15, - 16 )
