Question

The midpoint of UV is (5, –11). The coordinates of one endpoint are U(3, 5). Find the coordinates of endpoint V

Answer 1

co-ordinate of mid-point is average of co-ordinates of endpoints.
let V=(x,y)
so
(3+x)/2 = 5
can u find x from here ?

Answer 2

no..

Answer 3

multiply 2 to both sides, what u get ?

Answer 4

im confused..

Answer 5

what is 5*2 =?

Answer 6

10 lol.

Answer 7

so 3+x=10
x=10-3 = ??

Answer 8

huh?

Answer 9

7?

Answer 10

x=7. right :)
now y.
(5+y)/2=-11
y+5=-22
y= -22-5 = ??

Answer 11

-27..

Answer 12

thats your y.
so your point V will be (7,-27)

Answer 13

ooooohhhhhh thanksss haha

Answer 14

welcome :)
