We use the section formula:

$(x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

We substitute $x_1=3,x_2=16,y_1=2,y_2=21$ and m=5, n=9

$(x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})$

We simplify to get:

$(x,y)=(\frac{80+27}{14},\frac{105+10}{14})$

This simplifies to:

$(x,y)=(\frac{107}{14},\frac{125}{14})$

In decimals we get:

$(x,y)=(7.6,8.8)$
