Answer:

[tex]P = (\frac{8}{3},\frac{11}{3})[/tex]

Step-by-step explanation:

Given

[tex]X = (1,2)[/tex]

[tex]Y = (6,7)[/tex]

Required

The point at 1/3 of XY

If the point is at 1/3 for X, then the other end (to Y) is 2/3

So, we have:

[tex]m:n = 1/3:2/3[/tex]

Multiply by 3

[tex]m:n = 1:2[/tex]

The point (P) is calculated using:

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

This gives:

[tex]P = (\frac{1*6 + 2*1}{1+2},\frac{1*7 + 2*2}{1+2})[/tex]

[tex]P = (\frac{8}{3},\frac{11}{3})[/tex]
