Question

Find the coordinates of the other endpoint when you are given the midpoint and one of the endpoints. Answer in terms of a decimal rounded to the nearest tenth or an improper fraction in simplest form.

P1 M P2
(3, 5) (-2, 0) ( , )

Answer 1

i know i think its -5 , -7 butt show me howwww

Answer 2

let (x1, y1) be P2. so you'll need to solve these for the coordinates:

-2 = (3+x1)/2
0 = (5+y1)/2

in each, solve for the variable to get x1, y1 and that'll be the coordinates of P2

Answer 3

thanks so much!
