The midpoint of CD is E(–1, 0). One endpoint is C (5, 2). What are the coordinates of the other endpoint?

Answer 1

E is as far from C as it is from D. So,

CE = E-C = (-1-5,0-2) = (-6,-2)

So, add that much to E and you get
D = E+(E-C) = (-1,0)+(-6,-2) = (-7,-2)

Answer 2

Its increasing right? I think you should flip it, x_2-x_1 and y_2 - y_1. Put on a graph, the answer you wrote would make no sense really.

Answer 3

wouldnt it be (-7,-2)

Answer 4

the other guy was lazy i swear

Answer 5

mudosa

Answer 6

Uwu

Answer 7

Bro what is the answer… I- ☹️

Answer 8

go to desmos and put in
(-1,0) - (5,2) on the same line
It will give you -6,-2
add that to the original point
-6,-2+-1,0=-7,-2
that's it -7,-2 is the other point

Answer 9

Owo
