Question

The midpoint of Segment cd is E( -1,0). one end point is C(5,2). what are the other coordinates to the other end point??

Answer 1

\[Midpoint = \left( \frac{ x_{1}+x _{2} }{ 2 }, \frac{ y_{1}+y _{2} }{ 2 } \right)\]
So we know the midpoint is (-1,0).
We can use (5,2) as (x1,y1).

Answer 2

oh okay cause i was thinking i should use segment addition postulate equation
