Question

Find the other endpoint of the line segment if:

midpoint: (-10, -6) and one of the endpoints is: (-5, 4)

Answer 1

( - 15, - 16 )

Explanation:

Coordinates of midpoint are (
`(x_(1) +x_(2) )/(2)` ,
`(y_(1) +y_(2) )/(2)` )

( - 5 + x ) / 2 = - 10 ⇒ x = - 15

( 4 + y ) / 2 = - 6 ⇒ y = - 16

( - 15, - 16 )
