Answer:

the coordinates of the centroid of the triangle with the vertices A(-6,8), B(-3,1),andC(0,3).

={(-6-3-0)/3,(8+1+3)/3}=(-<em>3</em><em>,</em><em>4</em><em>)</em>

Answer:

<em>( - 3, 4 )  </em>

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 )

m_{AE} = - \frac{4}{3}

Equation of median AE is y = - \frac{4}{3} x

Solve system of equations:

y = - \frac{4}{3} x and x = - 3

<em>( - 3, 4 ) are coordinates of the centroid of the Δ ABC </em>
