Answer:

( - 3, 4 )  

Step-by-step explanation:

The centroid of a triangle is the intersection of the three medians of the triangle.

A ( - 6, 8 )

C ( 0, 3 )

Coordinates of the midpoint of AC are D( - 3, 5.5 )

Median BD is x = - 3

Coordinates of midpoint of BC are E( - 1.5, 2 )

[tex]m_{AE}[/tex] = - [tex]\frac{4}{3}[/tex]

Equation of median AE is y = - [tex]\frac{4}{3}[/tex] x

Solve system of equations:

y = - [tex]\frac{4}{3}[/tex] x and x = - 3

( - 3, 4 ) are coordinates of the centroid of the Δ ABC
