On a coordinate plane, a line is drawn from Rock to Tree. The x- and y-axes are labeled feet. Rock is at (3, 2) and Tree is at (16, 21).
A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marina traced the map onto a coordinate plane to find the exact location of the treasure.

x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1

y = (StartFraction m Over m + n EndFraction) (y 2 minus y 1) + y 1

What are the coordinates of the treasure? If necessary, round the coordinates to the nearest tenth.

(11.4, 14.2)
(7.6, 8.8)
(5.7, 7.5)
(10.2, 12.6)

Answer:

The second choice [tex](7.6,8.8)[/tex]

Step-by-step explanation:

We use the section formula:

[tex](x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})[/tex]

We substitute [tex]x_1=3,x_2=16,y_1=2,y_2=21[/tex] and m=5, n=9

[tex](x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})[/tex]

We simplify to get:

[tex](x,y)=(\frac{80+27}{14},\frac{105+10}{14})[/tex]

This simplifies to:

[tex](x,y)=(\frac{107}{14},\frac{125}{14})[/tex]

In decimals we get:

[tex](x,y)=(7.6,8.8)[/tex]
