Coordinates
posted by Enno on .
The midpoint of rectangle PTQW is (0.5,6). The coordinates of P are (3.5,6). What are the coordinates of Q?

let the other end point be (x,y)
so (x3.5)/2 = .5
x3.5 = 1
x = 2.5
(y+6)/2 = 6
y+6 = 12
y = 6
other point is (2.5 , 6) 
Thanks so much.....ur rite!

Ok, one more question. U see when u have (x3.5)/2 = .5
x3.5 = 1 (how did u get 1) 
@enno , there is 1 because :
we had : (x3.5)/2 = .5
multiplying 2 both sides
(x3.5)/2 *2 = .5 *2
x3.5 = 1
and then you can proceed easily.
if a/b = c
then a = bc
I hope it helped u though I helped u 1 year later :P
