A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]

  • The coordinate of S is: [tex](6,\frac{8}{3})[/tex]

Given that:

[tex]RS : ST = 5 : 1[/tex]

The coordinates of RT are not given. So, I will solve using a general explanation.

When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:

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

Assume the coordinate of R and T is:

[tex]R = (1,6)\\T = (7,2)[/tex]

[tex]RS : ST = 5 : 1[/tex] means:

[tex]m:n = 5:1[/tex]

So, point S is:

[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]

[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]

[tex]S = [6,\frac{8}{3}][/tex]

Hence, if the coordinates of R and T are:

[tex]R = (1,6)\\T = (7,2)[/tex]

And the line ratio is:

[tex]m:n = 5:1[/tex]

The coordinate of S is:

[tex]S = [6,\frac{8}{3}][/tex]
