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

the average of the endpoints is the midpoint

Answer 2

that is assume v is (x,y)
we have (x+3)/2=5
and (y+5)/2=-11

Answer 3

you have two equations to solve

Answer 4

Okay

Answer 5

So all I have to do is find what number plus 3, divided by 2, equals 5? And what number plus 5, divided by two, equals -11? (I'm sorry, I've never been good with math)

Answer 6

yep

Answer 7

Okie dokie!

Answer 8

x would be 7, right?

Answer 9

And y would be -22, right?

Answer 10

almost
(x+3)/2=5
means x+3=10
so x=10-3=7
(y+5)/2=-11
means y+5=-22
so y=-22-5=-27

Answer 11

Oh, yeah, it would be -27. Thanks! :D
