What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1? y = (StartFraction
Dominik [7]

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is \frac{5y_2+y_1}{6}

<h3>What is section formula ?</h3>

Let point P(x,y) cuts line joining point  A(x_1,y_1) and B(x_2,y_2)  in m_1:m_2 then coordinate of point P is equal to (\frac{m_1x_2+m_2x_1}{m_1+m_2}, \frac{m_1y_2+m_2y_1}{m_1+m_2})

Here given that point divides line segment from J to K into a ratio 5:1

So

m_1=5\\\\m_2=1

Now we have to fin y coordinate of point that divides the directed line segment from J to K into a ratio of 5:1

We can calculated y coordinate by applying section formula as :

\frac{5y_2+1y_1}{5+1}\\\\\frac{5y_2+y_1}{6}

By applying section formula we got that y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is \frac{5y_2+y_1}{6}
