One end of a line segment has coordinates (9,13). If the midpoint of the line segment is
(-6,2), what are coordinates of the other
endpoint?

(-21,-9)

Step-by-step explanation:

let other point be x2,y2

then apply mid point formula

x=(x1+x2)/2

y=(y1+y2)/2

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
