A segment with endpoints at $A(2, -2)$ and $B(14, 4)$ is extended through $B$ to point $C$. If $BC = \frac{1}{3} \cdot AB$, what are the coordinates for point $C$? Express your answer as an ordered pair.

A = (2, -2)    B  =(14,4)

 

BC = (1/3) AB

 

We can find the coordinates of  C thusly  :

 

( 14  + (1/3) ( 14 -2)  ,  4 + (1/3)(4 - -2) )  = 

 

(14+ 12/3   ,   4 + 6/3)   =

 

(14 + 4 ,  4 + 2)  =

 

(18,  6)
