Question

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

Answer 1

Answer:

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

E is as far from C as it is from D. So,CE = E-C = (-1-5,0-2) = (-6,-2)

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

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 getD = E+(E-C) = (-1,0)+(-6,-2) = (-7,-2)

Answer 2

Answer:

I think it is B.
