Question

segment MN has midpoint P if M has coordinates(14,-3) and P has coordinates (1,4) what are thecoordinates of N?

Answer 1

OK, well, we need to calculate the slope and the distance.

First, what's the slope?

Answer 2

I would use the midpoint formula
\[( (x _{1}+x _{2})/2, (y _{1}+y _{2})/2 )\]

Answer 3

So to find the x coordinate of N
\[(14+x _{2})/2=1\]

Answer 4

\[14+x _{2}=2\] \[x _{2}=-12\]
