The correct question is
<span>The midpoint of kl is m(–8, 1). one endpoint is k(–6, 5). find the coordinates of the other endpoint l.
we know that
the formula of midpoint is
Xm=(x1+x2)/2----> 2*Xm=x1+x2------> x2=2*Xm-x1
Ym=(y1+y2)/2----> </span>2*Ym=y1+y2------> y2=2*Ym-y1<span>
let
(x1,y1)-------> </span>(–6, 5).
(Xm,Ym)-----> (-8,1)
find (x2,y2)
x2=2*Xm-x1-----> 2*(-8)-(-6)----> -10
y2=2*Ym-y1----> 2*(1)-5-----> -3
the point l is (-10,-3)
Answer:
These are the correct positions
Honest opinion once cause its just one straight line
For the first one, see how the two triangles are alike since they included the same little dashes on them. So x is literally half of 18... for the second one (g,m) And (m,p) equal to 180 since they are on a 180 degree line .. and I kind of forgot how to solve the rest ... I hope this helped in any way
