Question 567425
(-1/3,1/3) and (-7/3,-5/3)
First, find the midpoint of the x-coordinates
{{{ ( -7/3 + (-1/3) ) / 2 }}}
---------------------
{{{ (-8/3) / 2 }}}
-------------
{{{ -8/6 = -4/3 }}}
----------------
Then find the midpoint of the y-coordinates
{{{ ( -5/3 + 1/3 ) / 2 }}}
-------------------
{{{ (-4/3)/2 }}}
-----------
{{{ -2/3 }}}
--------
The midpoint is (-4/3, -2/3 )
