Ian's home is represented by the point (4, 4) on the coordinate grid. Joe's home is represented by the point (10, 6) on the coordinate grid.

Given:

Ian's home coordinated = (4, 4)

Joe's home coordinated = ( 10, 6)

Ratio = 1:1

Find-:

The coordination of diner point

Explanation-:

Coordination of ratio point is:

Let coordination of P and Q is:


\begin{gathered} P=(x_1,y_1) \\ \\ Q=(x_2,y_2) \end{gathered}

So point S is:


S=((mx_2+nx_1)/(m+n),(my_2+ny_1)/(m+n))

Where,


\begin{gathered} P=(4,4) \\ \\ Q=(10,6) \\ \\ m:n=1:1 \end{gathered}

So the dinner point is:


\begin{gathered} =((10+4)/(1+1),(6+4)/(1+1)) \\ \\ =((14)/(2),(10)/(2)) \\ \\ =(7,5) \end{gathered}

Dinner point is: (7,5)

Ian's home is represented by the point (4, 4) on the coordinate grid. Joe's home is-example-1
