On a coordinate plane, point A divides the line segment BC with endpoints
B(-3, -2) and C(6,1) into a 2 to 1 ratio with AB being the longer part.
What are the coordinates of point ?

Respuesta :

The coordinate of point A that divides the line BC into ratio of 2 to 1 is (0, -1)

The midpoint formula to get the coordinate of point A is expressed as:

[tex]A(X,Y) = (\frac{ax_1+bx_2}{a+b}, \frac{ay_1+by_2}{a+b})[/tex]

Given the coordinates B(-3, -2) and C(6,1) divided into a ratio 2 to 1, the coordinate of point A on BC will be;

[tex]A(X,Y) = (\frac{2(-3)+1(6)}{2+1}, \frac{2(-2)+1(1)}{2+1})\\A(X,Y) = (\frac{-6+6}{3}, \frac{-4+1}{3})\\A(X,Y) = (\frac{0}{3}, \frac{-3}{3})\\A(X, Y) = (0, -1)[/tex]

Hence the coordinate of point A that divides the line BC into ratio of 2 to 1 is (0, -1)
