What are the coordinates of the centroid of a triangle with vertices P(−4, −1) , Q(2, 2) , and R(2, −3) ?

This is easy....the centroid is given by :

 

[ (  add the x coordinates of the vertices ) / 3, ( add the y coordinates of the vertices ) / 3 ]

 

So we have

 

[   ( -4 + 2 + 2 ) / 3  ,  ( -1 + 2 + -3 ) / 3  ]

 

[  0 / 3 ,  - 2/3  ]  

 

( 0 , - 2/3 )
