Question 1177340

Given the midpoint of a point is ({{{6}}}, {{{3}}}) and an endpoint is ({{{4}}}, {{{-2}}}). Find the other endpoint.

({{{6}}}, {{{3}}}) =({{{(4+x)/2}}}, ({{{-2+y)/2}}})

=>
{{{(4+x)/2=6}}}
{{{4+x=12}}}
{{{x=12-4}}}
{{{x=8}}}

{{{(-2+y)/2=3}}}
{{{-2+y=6}}}
{{{y=6+2}}}
{{{y=8}}}

the other endpoint is ({{{8}}},{{{8}}})
