Question

find the coordinates of T given that S is the midpoint of RT,R(-4,2) and S(6,8)

Answer 1

start:left end=(-4,2) & midpoint=(6,8), wanna find rite end

from left tu mid point: deltax=6--4=10 & deltay=8-2=6

rite end: add same deltas tu midpoint

x-rite=6+10=16

y-rite=8+6=14

rite end=(16,14)

Answer 2

Find the slope of the line*

*rise over run or y-y divided by x-x

then use that method
