Question

Find the coordinates of the other endpoint when you are given the midpoint and one of the endpoints.

P1 M P2
(12, 4) (2, 6)

Answer 1

i need to find p2

Answer 2

12 to 2 is ten left. another ten left is -8
4 to 6 is up 2, another 2 up gives 8
so answer is \((-8,8)\)

Answer 3

ohhhh... thansk!!
how about this one...
Find the coordinates of the other endpoint when you are given the midpoint and one of the endpoints.

P1 M P2
(-16, 0) (0, -16) would it be (0,16)

Answer 4

you can check that it is right, since \((\frac{12-8}{2},\frac{8+4}{2})\) is \((2,6)\)

Answer 5

ohhh thank u very much!

Answer 6

are you looking for the midpoint or the endpoint in your second question?

Answer 7

no. p2

Answer 8

ok so for first coordinate you need to solve
\[\frac{-16+x}{2}=0\] or \[-16+x=0\]
\[x=16\] so first coordinate is 16

Answer 9

oh ok

Answer 10

second coordinate solve
\[\frac{0+y}{2}=-16\]
\[\frac{y}{2}=-16\]
\[y=-32\] so your point is \((16,-32)\)

Answer 11

oh thanks! thanks! appreciate it
