Question 1150768
{{{R}}} is the midpoint of segment {{{PS}}}.

then
{{{P}}}.............................{{{R}}}..................................{{{S}}}


{{{ Q}}} is the midpoint of {{{RS}}}.

then
{{{P}}}..............................{{{R}}}...............{{{Q}}}...................{{{S}}}


if {{{P}}} is located at ({{{8}}},{{{10}}}) and {{{S}}} is located at ({{{12}}},{{{-6}}}). What are the coordinates of {{{Q}}}?

P(8,10)..............................R...............Q...................S(12,-6)

if {{{P}}} at ({{{8}}},{{{10}}}) and {{{S}}} at ({{{12}}},{{{-6}}}), coordinates of their midpoint are:

{{{R}}}({{{(8+12)/2}}},{{{(10-6)/2}}})=({{{10}}},{{{2}}})


and, the coordinates of {{{Q }}}will be:

 {{{Q}}}({{{(10+12)/2}}},{{{(2-6)/2}}})=({{{11}}},{{{-2}}})


answer: C. ({{{11}}},{{{-2}}})
