how do i find the other endpoint when the other Endpoint (5,0) and midpoint (-3,-5)?
The midpoint formula is: ((x1+x2)/2,(y1+y2)/2)
For the x part:
%285%2Bx%29%2F2=-3
2%285%2Bx%29%2F2=-3%2A2
5%2Bx=-6
-5%2B5%2Bx=-6-5
x=-11
For the y part:
%280%2By%29%2F2=-5
y%2F2=-5
2y%2F2=-5%2A2
y=-10
Therefore the other endpoint is: (x,y)=(-11,-10)
Happy Calculating!!!!
