The coordinates of the endpoints of directed line segment ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2, the coordinates of B are
Greeley [361]

Answer:

The coordinates of B are (1,-5).

Step-by-step explanation:

To find the coordinates of point B we will apply section formula.

Its used to find out if any line segment is of any m_1: m_2 ratios.

As the lie segment is joining the points internally we will use section formula for internal points.

Lets say that B is having coordinates (k,l) then k=\frac{m_1(x_2) +m_2(x_1)}{m_1+m_2} and l=\frac{m_1(y_2) +m_2(y_1)}{m_1+m_2}

Now we have A=(8,7) we call it (x_1,y_1) then C=(7,-13) we call it (x_2,y_2).

And m_1=3,m_2=2

Plugging all the values in section formula we have.

k=\frac{m_1(x_2) +m_2(x_1)}{m_1+m_2}

k=\frac{3(7) +2(-8)}{2+3}

= \frac{21-16}{5}= 1

Similarly

l=\frac{m_1(y_2) +m_2(y_1)}{m_1+m_2}

l=\frac{3(-13) +2(7)}{2+3}

l=\frac{-39+14}{5}= -5

So the coordinates of B =(1,-5)
